This is a photographic negative of six people in what appears to be a conference during an Oakland Oaks baseball game. In the middle of the group an umpire is motioning with his left arm by pointing with the mask in his hand. One Oak player (#10) has his back to the camera and is holding a bat. Another Oak, who is closer top the umpire than #10 has his hands straight out in front of him and on another Oak's shoulders. The two of Oaks are in behind the rest watching the conference. In the background the third base side can be seen.
