I like trivia that makes you think for a while before you get the answer. Hate trivia that can be easily looked up on-line. So, let's see how good you are:
Postwar Baseball cards (Topps 1952 - 1980):
1) The set containing the most rookie cards of 20 game winners had 8. Name the set, and of course I'd expect you to name the pitchers involved.
Bonus question: There were two other sets that contained the rookie cards of 7 twenty game winners. Interestingly the two sets with 7 and the one set with 8 all ran consecutively. Name the two sets with 7, and of course I'd want you to name the corresponding players.
