I have 2 of those... Derringer, and Joe Brown. Derringer was from Kentucky, he appeared in 4 World Series, 1931, 1939, 1940, & 1945. Those measure 8x10.
And I have these two photos. I've yet to figure out if they're 1929 or 1930, Rochester won both years. May well be an HOFer in that team photo. The player is Paul Derringer.
