This is gorgeous.
Painted by noted sports artist Arthur K. Miller, featured above is a Duke Snider "Card that Never Was" showing him on a 1948 Leaf Baseball card design. It is currently on auction at Heritage (Auction Link Here).
Duke Snider had spent a few months in Brooklyn in 1947, and if the card hobby was anything like what we have today he would have had an Baseball card to call his own the following year. Heck, collectors would have had some cardboard gold to put in their album when he first signed with the franchise.
