As I am going through piles of odds and ends to try to get my collection in order I found this "card". I need to put a date with it and categorize it but have little info. It looks like it was part of a game at one time. The sleeve it is in has the wording "San Juaquin Valley League 1910-1911." I don't think the guys in the stands have hats on that would date it to being that old, but I am not sure. Any help on the approximate year or other info will be appreciated. For now I have it as "WG-Unc, 1940s".....(the date is anyone's guess) thanks!!
