The 1993 Upper Deck All-Time Heroes of Baseball set is a specialized release primarily known for its unique triple-folding design, which pays homage to the classic 1912 T-202 Hassan Triple Folders. The "T-Series" specifically refers to the cards contained within the standard foil packs of this set, which featured 12 cards per pack.
