Here's one from the pile of envelopes (with about 7-12 each) in a wrap labeled "1912 Europe" (he was married in 1912). I really like this one for some reason. Most of the others so far aren't as interesting (and maybe my great-grandmother took this one instead - she was a painter as well as a bacteriologist). This is on the larger roll film (mentioned earlier, film about 90mm wide, image 83mm x 140mm).
I haven't done any others from this group, yet, I've been doing the baby pictures and shots of my grandmother and her sisters. There's also a trip to England (and maybe more) on smaller film from the 30s.
