Hello- I was pointed to this forum by several people that I had reached out to while doing research on a printed product from the late 1940's. I am hoping to get some skilled eyes on the prints to 1. validate that a change was made at the production level and 2. that the kind of change that I think was made, would have been done in commercial printed products. The product is a set of baseball cards distributed by the Leaf Company out of Chicago in 1948/49. There are variations that are present that the "Card Industry" chalks up do "Printer Errors", but I actually think there was a second printing, and physical changes were made to the plates to try and make the cards more colorful and appealing after a lackluster reception with the first run. Any help would be appreciated. I have attached a quick PDF that outlines my theory.
