This image was taken of Christy Mathewson at the 1911 World Series. Matty is seen warming up in his black uniform, only worn during the 1911 World Series, prior to a game in the Polo Grounds. This photo was by Brown Brothers, their 108 Fulton stamp was only used between 1904 and 1915. This photo was taken only a few moments apart from this George Grantham Bain image which is in the Library of Congress Bain collection. It is a rare instance where as here another photographer captured a better image of a scene than Bain.
