Graded GOOD 30 by SGC. Very attractive example of New York Giants Hall of Famer Christy Mathewson from the prized "Blue Background" series of the M116 Sporting Life set, one of the most popular of all 1910-era issues. M116s have always been highly appreciated by collectors for their distinctive style and rarity relative to the more commonly seen tobacco cards of the era. Christy Mathewson is one of the key cards of the series, and the offered example features the portrait of Mathewson set against a blue background. M116 Sporting Life cards were issued in sets of twelve cards per series, and the Blue Background cards are by far the most desirable combination of series within the entire set. These twenty-four cards were issued with both blue backgrounds and white backgrounds. The Blue Background cards have always been especially appreciated by collectors for their scarcity and distinctive style. Technically in a very modest grade, the card is bright and clean both front and back, with outstanding color, flawless registration, even corner wear, a few creases, and an extremely bold blue background. The Sporting Life advertisement on the reverse is entirely clean and boldly printed. This is a magnificent example in a very desirable and relatively affordable mid-grade of one of Christy Mathewson's most distinctive and popular portrait cards. Reserve $200. Estimate (open).
