An artifact from the very first year of Topps baseball card production, an unopened wax pack of 1951 Topps "Red Back" cards, containing two cards offered for the super low price of one penny. With a fairly tight seal, the pack was submitted by us to PSA and recently graded NM 7.  Colorful, green-and-red graphics tout "Doubles Playing Cards," with no mention of the ballplayers contained therein.  A vintage pack from the dawn of the hobby's Golden Age.
