Vintage image of Hall of Fame pitcher Christy Mathewson during warmups circa 1911. In dark uniform, the right-hander has hands behind head at the top of his windup as fans file in. Exceptionally well-preserved with no visible creases or blemishes, undated pencil caption on back notes, "taken at a World Series game" along with notations and stamps from Brown Brothers, as this originates from their archive which dates back over a century. PSA Type I encapsulated.
