Original Type I photograph of New York Giants manager John McGraw on the field at the Polo Grounds. McGraw is pictured posing for the camera during pregame warmup. Six Brown Brothers credit stamps appear on the reverse, along with McGraw's name written in pencil. Although no year is listed, the uniform style shown here was used by the Giants only in 1912. The photo measures 6x4.5" and displays a few light creases, as well as a tiny tear along the upper left border. Very Good condition overall. Culled from the Legendary Brown Brothers Photo Archive. PSA encapsulated as Type I Authentic.
