Have been sorting through my dads massive card collection over the last few years. thousands and thousands of cards from the 50s/60s. yesterday i came across a binder that had these in them, they seem to be authentic to the 60s but cant find anything on ebay to comp them with. the backs are empty and there are crease lines like they had once been folded. Figured id ask the pros, anyone know what these are? regular baseball card there for size reference. thanks!
