How it helps
Use it for a focused task
A step-by-step decision helper that narrows down the likely decade of an undated vintage postcard based on visual and printing features you can observe. Select the features you see on your postcard and the identifier will show the most likely era range with historical context, reference cues, and confidence notes.
Start with the back of the postcard. Choose the back layout (undivided, divided, or printed message area).
Then work through font style, color process, stamp box design, and paper texture. Each selection narrows the date range.
