Unopened 1975 Topps mini baseball rack pack of 42 cards with a George Brett Rookie card visible at the center of right stack. Consignor originally bought cases of rack packs back in 1975 to build sets to sell.(In Southern California the 75 Topps minis were only sold in rack packs at select Savon Drug stores) From opening and sorting so many cards consignor learned the sequence leading to the Brett Rookie. When he found a stack with Darrell Porter showing he knew there would be a George Brett Rookie a few cards below. Thus he held this pack back unopened. A Fred Lynn Rookie is also present on the bottom of pack. Pack in great condition.
