I am trying to find out from anyone on here if the original printing plates from baseball cards pre 1960 have ever been found or made available to purchase at auction. The reason I am asking is I found at the Chicago National about 10 years ago a curved zinc printing plate that had 8 small cards? baseball player images on them from 1932-36 era They were similiar to the 1934 (R310) butterfinger issue, with signatures, but small, like 1/2 the size of a T206.
I am very curious if ANY pre war card printing plates have EVER been found?? Please replyMORE PICS SEE BELOW REPLY
