This is it. The end. There is no more, after one final card.
1933 Goudey #94 Bill Walker
Now clearly, this card isn't in great shape, but it's over 80 years old! This is easily the oldest card in my collection, beating the previous oldest by 20 years. At first I assumed this must have been from the reprint set from 1983, but it doesn't have the telltale "Galasso" mark on the back. Bill Walker was actually from East St. Louis, IL. After a few years with the New York Giants, he played for the Cardinals from 1933-1936, with one All-Star game appearance in 1935.
A big final Thank You to Junior Junkie for the giant box of cards, tailored perfectly to my collection.
