None are famous, that I know of. The few that I have are from in and around my local area, which is faily small. Many are photographer unknown with some having studio names on them. Methinks this calls for a trip to the historical society.

I would say you would need to note they are not your images and are reproductions of others work.
I guess while it may seem obvious to me (what with the fact that various buildings are now gone) that is an interesting thing to mention.
