At the time this set was issued, Ted Williams and Mickey Mantle were under exclusive contract to Upper Deck, so the two Ted Williams cards (#1 and #250) and the Mickey Mantle fantasy card (#259) were issued as inserts in packs of 1994 Upper Deck All-Time Heroes. So the only way to put together a complete set of this Topps product, you had to buy packs of Upper Deck and hope for the best. Those three cards are much harder to acquire than the rest of the set. This is a near set, but it already has the hardest three. There are also two spots being "held" but gold cards instead of base, plus an additional 45 gold cards.
