I like this concept a lot. I've been fascinated for years with the player selection practices of the three major card companies of the '80s. Pitcher Marty Bystrom was clutch for the Phillies during their 1980 World Series run, but he only merited a co-starring role on a Phillies Future Stars card with Jim Wright and Jay Loviglio. And how does John Vukovich end up in the 1981 Fleer set, but not in the Topps or Donruss sets?
Kevin correctly mentions in his Phillies post that Ryne Sandberg had no baseball cards in the 1981 sets, which is why I decided to make one of my own.
I'm definitely looking forward to following Kevin's progress as he builds his ultimate card set.
