A postcard can be a travel souvenir, a printed view, a family message, an advertising piece, or a small record of military and social history. This postcard collecting guide explains how to identify common types, estimate a card’s era, record its condition, and organize a collection so each new find can be researched and enjoyed rather than placed in an unmarked box.
Overview
The most useful way to identify an old postcard is to consider several clues together: the image, printing style, back design, message, postmark, publisher information, and physical condition. No single feature always provides an exact date. A modern reproduction may copy an older image, while an older card may have been mailed long after it was printed.
Begin by separating identification from valuation. First determine what the card is and when it was probably made. Then investigate scarcity, demand, condition, and comparable examples. A visually attractive card is not automatically rare, and an inexpensive-looking card may be important because it documents a local business, vanished building, family event, military unit, or unusual subject.
Collectors commonly organize postcards by place, subject, period, publisher, artist, printing method, or a combination of these. A small collection might focus on one town or a family archive. A larger collection may use broad categories such as travel, holidays, advertising, transportation, military history, occupations, disasters, architecture, and artist-signed designs.
What to track
Postcard types and printing styles
Use the following descriptions as a starting point, not as a substitute for examining the individual card:
| Type or feature | Identification clues | What to record |
|---|---|---|
| Undivided-back card | The reverse is generally reserved for an address, leaving little or no designated writing area beside it. | Back layout, message placement, postmark, and any printed notice. |
| Divided-back card | A vertical dividing line separates the address area from the message area. | Whether the card was mailed, the date of the postmark, and publisher text. |
| Linen card | A textured, often somewhat coarse surface and strong colors; many feature travel views, landmarks, or commercial scenes. | Surface texture, color treatment, location, caption, and maker. |
| Chrome card | A smooth, glossy photographic appearance commonly associated with later twentieth-century travel and souvenir cards. | Gloss, printed copyright line, location, and any modern reproduction clues. |
| Real-photo postcard | An actual photographic image printed onto postcard stock, often with variable contrast, handwritten titles, or a local photographer’s mark. | Image subject, photographer, studio information, paper texture, and evidence of a genuine photographic print. |
| Artist-signed card | An artist’s name, initials, monogram, or printed signature appears in the image or margin. | Exact signature, placement, publisher, artwork style, and whether the signature is printed or handwritten. |
| Advertising card | Promotes a product, hotel, theater, railway, shop, event, or service rather than simply presenting a scenic view. | Business name, slogan, address, product, and apparent period of operation. |
Holiday, military, and travel cards are themes rather than printing processes. A Christmas card may be linen, chrome, or real-photo. A military card may show a portrait, camp, ship, patriotic artwork, or a handwritten message from a service member. Travel cards may depict a hotel, national park, railway, resort, city street, or roadside attraction. Record both the theme and the physical type.
Dating clues and terminology
When learning how to identify old postcards, inspect the reverse before relying on visual style. An undivided back can suggest an earlier postcard format, while a divided back narrows the possible period but does not prove a precise year. A dated postmark is useful evidence of when the card was mailed, though the printing may have occurred earlier. Messages, addresses, stamps, clothing, automobiles, architecture, and business names can provide additional context.
Publishers often printed their names, series numbers, copyright notices, or location information in small type. Photograph the front and back at a readable resolution, then search distinctive wording in quotation marks. For a local view, combine the town name with the building, street, hotel, railway, or business shown. Local historical societies, library image collections, newspaper archives, city directories, and regional postcard clubs can be more useful than a broad image search.
Keep a distinction between “postmarked,” “mailed,” and “written.” A card may have a postmark but no message, or writing without a legible cancellation. Note uncertainty with terms such as “about,” “possibly,” or “date unknown” instead of forcing a precise attribution.
Condition labels
Condition should be recorded consistently. Check corners, edges, surface gloss, creases, stains, fading, album residue, writing, adhesive, trimming, and image clarity. A simple internal system might use:
- Very fine: clean and sharp with only minor handling evidence.
- Fine: attractive overall, with light wear or a small imperfection.
- Good: usable and identifiable, but with noticeable corner, edge, surface, or paper wear.
- Fair: substantial wear, staining, creasing, fading, or writing, while the subject remains legible.
- Poor: heavily damaged, altered, incomplete, or difficult to read.
These labels are descriptive rather than universal grading standards. Add specific notes instead of relying on a grade alone. A scarce real-photo card with writing may be more historically meaningful than a common clean scenic card, so condition should be considered alongside subject and provenance.
Collection-inventory template
A spreadsheet or catalog record can include the following fields:
- Inventory number and storage location
- Front caption and exact subject
- Town, region, country, building, or event shown
- Postcard type and printing style
- Publisher, printer, photographer, artist, and series number
- Estimated date and evidence for that estimate
- Postmark date, stamp, sender, recipient, and transcription of important text
- Condition and notable defects
- Purchase source, previous owner, and acquisition date
- Duplicates, trade status, research links, and image filenames
Use one record per card, even when several cards arrive as a group. For duplicate cards, compare more than the image: one may have a different publisher, back layout, postmark, message, or color treatment.
Cadence and checkpoints
Catalog new cards shortly after acquisition, while their source and context are still clear. At that first checkpoint, photograph both sides, assign a temporary inventory number, remove loose packaging, and place the card in an archival sleeve. Do not trim, clean, erase, laminate, or apply tape to improve appearance.
Once a month or quarter, review uncataloged material in manageable batches. Check whether provisional dates can be improved, whether a location has been misidentified, and whether duplicates belong in a separate trade or gift group. Compare notes across cards from the same publisher or town; repeated series numbers and design conventions can reveal relationships that are not obvious from one card.
Every few months, audit storage. Look for bending, dust, moisture, fading, insects, adhesive failure, or cards pressed tightly together. Store cards vertically or flat according to the size and quantity, using acid-free, lignin-free materials when available. Keep them away from direct sunlight, damp areas, extreme temperature changes, and PVC plastics.

Once a year, review your collecting theme. You may discover that a broad “travel” group is becoming a focused collection of railway stations, coastal resorts, or one county’s vanished buildings. Update category names, research notes, and duplicate lists so the catalog reflects how you actually collect.
How to interpret changes
New information should change a catalog record gradually, not erase the reasoning behind it. If a directory confirms the address of an advertised business, retain the original note and add the new source and date. If a postmark clarifies when a card was mailed, record that date separately from the estimated printing date.
When researching postcard values, avoid treating an asking price as proof of market value. Compare cards with similar subject, type, condition, publisher, and completeness. A rare location may attract specialist interest, while a common view may be valuable to a local-history collector because of its message or documentary detail. The same principle applies when comparing vintage collectibles generally: identification, condition, authenticity, and evidence of demand should be considered together. The site’s Vintage Collectibles Value Guide offers a broader framework for that research.
Be especially cautious with real-photo cards, unusual local scenes, signed cards, and advertising ephemera. These categories can reward close inspection, but visual appearance alone does not establish age or authenticity. Compare paper, printing, handwriting, photographic detail, and provenance. If a card appears unusually important or expensive, seek a second opinion from a specialist, regional archive, or established collecting organization before making a major purchase.
Organizing changes can also reveal the story of the collection itself. A group acquired from one estate may contain family correspondence, while cards purchased at different times may document changing views of the same place. Preserve those connections in the notes. The history of ownership is part of the object’s context.
When to revisit
Return to this guide whenever you acquire an unsorted box, inherit a family album, or begin a new postcard theme. Revisit the catalog monthly or quarterly if you are actively buying and trading; a twice-yearly review may be enough for a stable personal collection. Update records when you find a clearer publisher mark, confirm a location, discover a related card, or change the way you organize duplicates.
Before buying, use your inventory to search for duplicates and gaps. Before selling or trading, export a copy of the relevant records and photograph each card again. Before gifting a card, include its subject, approximate date, and any known story so the recipient receives a historical keepsake rather than an unidentified piece of paper.
Your next practical step is simple: choose ten cards, photograph both sides, complete the inventory fields, assign condition notes, and place them in labeled archival sleeves. After that first batch, the rest of the collection becomes easier to understand, search, preserve, and revisit.
