How to label a photo strip when the date is unknown
Separate evidence, recollection and visual guesses in a useful caption.
A familiar hairstyle can suggest a decade without proving a year. An old strip becomes more useful when its label tells a future reader how the date was established, rather than presenting every estimate with equal certainty.
Use the object’s companions
Make a two-column worksheet: evidence beside the object, and your proposed date. Begin with a dated envelope or an album caption already associated with the strip. Record that relationship before separating anything. Leave the proposed date blank if the evidence does not support one.
Write a range when that is what you know
A note might read: probably summer 1988–1990; based on a family recollection recorded in 2026. Keep a clothing-based estimate separate from a date printed on the object. If two sources disagree, preserve both explanations. The absence of a known year is not a defect that needs an invented precise answer.
Make uncertainty searchable
In your folder or catalogue, use an unknown-date field instead of putting a guess into the file’s creation metadata as fact. Keep the scan date separately. That way a search for newly scanned pictures will not turn into a misleading timeline of when the original sessions happened.
