Thanks, Ole! That's a very good idea.

The reason for my interest is because I'm thinking of shooting 1920s vintage cars with 1920s vintage gear (except for the film) on 5x7, and selling the prints. I'm around those kinds of cars a lot, and at some of those shows already, and I've got a feeling (still asking around to confirm it) that such a product would be very popular, at least until everybody had a contact print or two or three of their vehicle and themselves (perhaps in vintage clothing).
