Robert, Photograph depicts a game at the House of Refuge in Rochester, New York. c. 1874
View is similar to other stereoviews attributed to Rochester famous photographer F.W. Bacon, that depict a game between "Colored" and "White" youths at the same facility. (Lots#232/233 - Mark Rucker's Collection Auction, November 1995)
Early images depicting black players in action are pretty difficult to find.
Hope this helps!
