My dad was given, and passed to me, a couple baseballs that were signed in the 30s. One was of the San Francisco Seals. Those autographs are a little faded and outside of Dom DiMaggio I am unfamiliar with most.

But, the other is from a team that went to Japan in the late 30s. Joe and Dom D, Tony Lazzeri, Lefty Gomez to high-grade. Sam Mele, Joe Marty, and others from the second tier.
