What I think you have there is a snapshot from the California Winter League circa 1928. There was a negro team called the Philadelphia Giants and those uniforms are a dead ringer for photos I have seen. Biz Mackey, Turkey Stearnes and Bullet Joe Rogan all played for the Giants around this time and they competed against white teams who had major and minor leaguers on them. I know of no team either here in the states or in Latin America Robinson played on called the Giants. Campy of course played for the Elite Giants but those uniforms were totally different than these. I have to get a root canal in an hour so I can't do any extensive research until later tonight.
