The cards in this 752-card set measure 2 1/2" by 3 1/2". The 1971 Topps set is a challenge to complete in strict mint condition because the black obverse border is easily scratched and damaged. An unusual feature of this set is that the player is also pictured in black and white on the back of the card. Featured subsets within this set include League Leaders (61-72), Playoffs cards (195-202), and World Series cards (327-332). Cards 524-643 and the last series (644-752) are somewhat scarce. The last series was printed in two sheets of 132. On the printing sheets 44 cards were printed in 50 percent greater quantity than the other 66 cards. These 66 (slightly) shorter-printed numbers are identified in the checklist below by SP. The key Rookie Cards in this set are the multi-player Rookie Card of Dusty Baker and Don Baylor and the individual cards of Bert Blyleven, Dave Concepcion, Steve Garvey, and Ted Simmons. The Jim Northrup and Jim Nash cards have been seen with our without printing "blotches" on the card. There is still debate on whether those two cards are just printing issues or legitimate variations. Among the ways these cards were issued were in 54-card rack packs which retailed for 39 cents.
