Grouping of six factory-sealed boxes from the 1994 Upper Deck All-Time Heroes of Baseball issue.  Celebrating the 125th Anniversary of Major League Baseball, the base set contained only retired players.  Each box contains 24 packs, with ten cards to a pack.  Potential autographed insert cards include Mickey Mantle, Tom Seaver, Reggie Jackson and George Brett, each of whom autographed 1,000 copies of their card for random insertion into one of the company''s future sets.  Boxes appear strong, though close examination will reveal small, insignificant flaws like tiny tears or separations in the plastic, wear at the edges or corners, etc.  Six boxes total.
