For example, here's a picture from 1918 of my paternal great grandmother, Ethel Modena Martindale Hunt, and two other ladies (I don't know who they are). The photo was printed onto a postcard (which is apparent on the back). Written in pen on the back is "Ethel Hunt on the right" and "1918."

I just wish that I'd seen this photo while Great Grandma Ethel was still alive so I could have asked her about it!
