Roar--did it involve a reproduction or likenesses of his cards ?
Andy-- were the cards detachable on the McGraw ?
As a Cardinals guy I hate to admit this but the Cubs, did a great thing a couple of years ago, teaming with Topps to create a unique set of cards depicting current and past Cub players in the format of older Topps cards, similar to the Archive issues. The set was issued whole to season thicket holders, and given out in partial lots to fans attending 4 games during the season. A really cool promotion that I wish the Cardinals would copy
