Just a shot in the dark...but does the photo that you have an opportunity to purchase look like this one?
When I read that it is a Culver photo, I thought George Grantham Bain photo. Culver acquired a lot of Bain's old photos and many are over-stamped with Culver ink.
If it is an original Bain (or any original from 1911), it would be a good buy at $50...IMHO.
Would like to see your photo.
