International art-postcard publisher and series maker Treat the card as both a collectible object and a historical document. Scan both sides before assigning a date, publisher, or value.
Identification workflow
- Transcribe caption, publisher, series, number, and printed text exactly.
- Record whether the back is private-mailing, undivided, divided, or modern.
- Describe stock, border, texture, color process, gloss, and photographic traits.
- Read the postmark and stamp while remembering mailing and printing dates can differ.
- Research the town, building, business, route, event, or person.
Dating the card
Era terms are useful because production conventions changed. Smithsonian guidance cautions that these periods are broad generalizations rather than concrete dates for every card. Publisher archives, production numbers, paper marks, captions, postmarks, and local history can refine the range.
What affects collector demand
The exact subject often matters more than age. Small-town views, vanished businesses, unusual transportation, scarce events, early real photo images, famous artists, and desirable publishers can attract specialists. Condition and completed-sale evidence remain essential.
Research checklist
- Search the exact caption in quotation marks.
- Try historical and modern place-name spellings.
- Compare publisher and production numbers.
- Use libraries, historical societies, maps, newspapers, and directories.
- Compare sold examples with the same view and condition.
