In mid-2001, Upper Deck released a product named SP Game Bat Milestone Edition. Inside each pack was a Milestone, International, Bound for the Hall, Autographed, or multi-player game bat card. While the first three sets on that list represented the most common pulls (They also had a gold parallel numbered to 35), the autographed and multi-player cards were very difficult to pull, seeded at 1 in 100 packs and 1 in 50 packs respectively. The multi-player cards I speak of feature either three (as pictured) or four players per card. This card of Paul O’Neill, David Justice, and Roger Clemens is just one of 14 Trios available.
