The Mickey Mouse bubblegum cards blazed a trail for cartoon cards, and here's an uncut sheet of colorful cards #49-#72 issued in 1935, just seven years after the extremely popular rodent made his debut in the animated feature "Steamboat Willie." There were originally 96 cards in this set, so this strip represents one-quarter of the content. Some of cards appear that they could be 9s or better. Some creases noticed in both upper corners and in card no. 64 and 70.
