This is a photographic negative of an Oakland Oaks baseball game. In this photo the umpire is walking away from an Oaks player and the catcher. The umpire has his mask off and is holding it in his left hand. The Oak player behind him is only a couple feet away and looking at the umpire. The front of both men can be seen here. The catcher is still in his stance and wearing his mask. In the background a few players are awaiting their chance at bat. Behind all of the players is the first base side stands. The stands are nearly full.
