This is a pretty neat team signed baseball. The key autograph on the baseball is that of HOF player Nellie Fox. This baseball dates to when Fox's rookie year as a White Sox. Additionally, this baseball is an official White Sox baseball. The ball is missing the autograph of Minnie Minoso who's rookie year was 1951. Due to that omission, we are fairly certain this is a 1950 ball as that is the only year that Fox was on the White Sox without Minnie Minoso.
