Includes (1) 1972 Topps Football cards pictured.  Cards are from a "fun pack"; see pictures for condition.  The 1972 Topps Football card set would be the first and only time that a football card set was issued in three series. However, the decision to include a third series seems to have been made at the last minute. There were no checklists for the new series as there had been in previous years, and the final series has long been a very scarce issue. In the end, the set contained 351 cards, which made it the largest football card set ever released up until that time.
