Great circa early 1910s portrait image of New York Giants Hall of Fame great Christy Mathewson in this original, one-of-a-kind, from-the-camera glass plate negative. Matty is front and center in this 7x5" head-and-shoulders portrait shot, with a wonderful image of the five-time holder of the National League's ERA between 1905 and 1913. Wonderful history courtesy of the Brown Brothers, who started their substantial photo aggregation service in 1904.
