Like the Blue Backs, the Topps Red Backs which were sold at the same time came two to a package for 1U. Their black-and-white photographs appear on a red, white, blue, and yellow background. The back printing is red on white. Their 2" X 2-5/8" size is the same as Blue Backs. Also identical is the set size (52 cards) and the game situations to be found on the fronts of the cards, for use in playing a card game of baseball. Red Backs are more common than Blue Backs by virtue of a 1980s discovery of a large hoard of unopened boxesl. Red Backs are also known to have been sold in a plastic-bagged set along with a foldout paper game board for 29 cents. HOFer Early Wynn is pictured on this example graded MINT by PSA.
