I picked up these 2002 Upper Deck All-Star Home Run Derby cards a few years ago on ebay. The cards feature pieces of the jerseys that the players wore while competing in the 2001 Home Run Derby. There were more than 5 players in the 2001 Home Run Derby, but I'm pretty sure these are the only 5 players included in this set.
Alex Rodriguez
Todd Helton
Bret Boone
Sammy Sosa
Jason Giambi
