This printing block is 3.5″ x 3.25″. I am not certain that this is for the Keystone company that produced toys and cameras but it is likely. The Indian boy has on a sailor’s cap that says USS Keystone and the feather in the cap has a K that is the same font used by Keystone in the 1950’s. He is holding a movie camera. I think the block dates from the 1950’s and was used for camera sales material but is it from Keystone Manufacturing before the company split in 1954 or after?
