For those of you who are not familiar with these, they are probably photos (reversed) of printing blocks. I have a bunch of these here and they are nearly worthless. If you has an early Coca Cola, it would MAYBE worth $100 to a hardcore collector. This whole lot is worth maybe $25, and frankly, I would not even pay that for it as there is no one out there that can really make use out of printing cuts of mom and pop stores. i have some for Texaco, etc and they are equally worthless.
They claim that they are for leather tooling, but I doubt it for a couple reasons. 1) who would Stamp "smith-Faus Drug Co" on a belt and 2) The backs are made of wood. Hit once and they will split or smash. A leather die would have to be much more durable. If these were leather dies, they would be equally valueless....
