143.1956 Topps NFL Football set1956 Topps Football is the company's first officially licensed NFL trading card product. This came as a result of the acquisition of their long-time competitor Bowman. This inaugural release was the start of an annual issue of Topps NFL football cards that continues today. It was printed in a single series of 120, though all the players (and team cards) from the Washington Redskins and Chicago Cardinals were short-printed, and are considered scarce as they were printed in much smaller quantities than other cards in the set. There is also an unnumbered checklist, as well as 5 contest cards that were included in packs (I have the checklist card). My raw set would grade about Ex/Mt to Nm.
