I have a friend that owned an antique collectible store. Someone brought in a few items that I later bought from him. I have a set of slides of movie posters is the best way to describe them. On the folder it says movie poster transparencies. Each slide says Kodak epr 3351, google has zero hits for “Kodak epr 3351.” I’m holding them up to my kitchen light. They are about 3”x5”.
Hopefully threes photos work. Any help would be appreciated. Thanks.
