Upper Deck released this high-end one card per pack "Holoview" set of 60 subjects in 1996, so this factory sealed Hobby Box of 36 packs represents, in theory at least, 60 percent of the set. The big attractions here are the autographed variations of the Ken Griffey Commemorative and Mike Piazza Tribute inserts, which were seeded one every 2,000 packs.
