These photos were quite the find for me! They are all purchased from an Ebay seller in Great Britain. None of them have names on them.
This is a photo postcard made somewhere in Europe. The print on the back is primarily English, but also French and German. There is no handwriting.
This one is possibly from France. ("carte postale" on back) No handwriting.
I don't know for sure whether this is one family, but there is such a family resemblance among many of these girls and young women that I wanted to include it.
This is an Azo photo postcard; I don't know if that means it's from any particular country. I am guessing North America though due to the wooden house behind.
