1994-98 Sports Heroes Feats & Facts - Baseball Champions
This is a multi-sport oversized mail order issue that has subsets for Baseball, Basketball, Football, etc. The Baseball Champions subset is numbered in the upper right corner and the back has copyright information including the Packet it was distributed in. Starter sets included 17 Packets with 12 cards each. Subsequent packets arrived in the mail on a monthly basis as long as the collector continued to pay. If a player changed teams or stats were updated, the entire packet would get updated and the Packet numbering would change. MrMopar has some great info on the variations this created.
This checklist is a work in progress and new variations will get added as they are found.
