No where near prewar, but I picked up a large grouping of press passes and pins from the early 70s at an estate auction. The estate owner worked for a sports communications company and attended a ton of sporting events ranging from 1972 to 1976, including world series games, superbowls, NCAA tournaments, college bowl games, NBA all star games, and many golf and tennis tournaments. One of the neater items, is a Arnold Palmer signature on a small piece of letterhead for the 1974 PGA championship. There are also press passes to the 1976 World Series and NLCS, and boxing press passes to a couple of Ali fights, and Frazier Foreman fight.
