Notes
Distributed to attendees of the 1991 WLAF World Bowl in London. #1-25 and #27 are identical to 1991 Pro Set's "World League Collectibles" insert, and #34-43 are renumbered and updated versions of 1991 Pro Set's "WL Helmet Collectibles" insert, with "World Bowl Collectible" printed above the card number (instead of "WL Helmet Collectible") on the lower back, and a team chronology (instead of the team's schedule) printed on the back. #33 is exclusive to this set.
