Exceptional rarity! Only PSA 9 example! This incredible 68 year old cello pack has somehow remained unopened and in mint condition over the past 7 decades since it rolled off the production line. Topps first regular issue professional football set featured stars like Blanda, Gifford, Grier, “Crazy Legs” Hirsch, and numerous other HOFers. Only 7 ’56 cellos have ever been authenticated by PSA, making it one of the rarest packs of the era, with this being the lone PSA 9 example.
