As this set was one of the last sets Fleer produced before going bankrupt, many cards listed on checklists are not believed to exist (most of which packed out as exchange cards). Here is a list I've compiled with data from other Fleer Greats of the Game collectors of the cards not believed to exist. I have suspicions about a few others as well, but looking for more confirmation on those. Anyone having a scan of any of these cards, please upload it and contact me. CluelessJoe

This is a terrific set to assemble HOF autographs and the card stock and style make it a great ttm autograph card. The variations and inserts make this set much larger than the 145 base cards. The set is estimated to contain over 700 unique cards inclusive of variations and 1/1 cards.
