This is a photographic negative of an Oakland Oaks player sliding into home plate. The base runner (#10) is getting up from his slide and dust is all around him. The catcher (#28) is standing above him, with his back to him, and with his arms out. The pitcher (#6) on the right of the negative appears to be walking back to the pitcher's mound. The umpire in the photo has his right hand up in the air like he is making the decision that the base runner is out.
