Rare and historically significant CDV of the 1875 Hartford Blues, including Hall of Fame pitcher Candy Cummings. Graded VG 3 by PSA. This is the only 1875 Hartford Blues CDV ever evaluated by PSA. The offered example is also the plate specimen for Mark Rucker's groundbreaking book Base Ball Cartes: The First Baseball Cards, published in 1988, and once resided in Rucker's personal collection. The formal studio photo pictures ten members of the club posing together in uniform, including Cummings (standing in the center) and player/manager Bob "Death to Flying Things" Ferguson (seated in the center). The photographer's name and city, "Prescott & White - Hartford," is printed on the reverse. Candy Cummings, in addition to being one of the top pitchers of the National Association (baseball's first professional league), and a member of baseball's Hall of Fame, is best known today as the inventor of the curve ball. Surprisingly, despite his widespread fame, photos of Cummings are practically nonexistent. This CDV is one of the very few known images of Cummings dating to his playing career. The 1875 Hartford Blues team CDV is well known but exceedingly rare. This is just the third example we have ever offered and we cannot recall having seen more than a few others over the years. Cummings enjoyed the finest season of his career in 1875. As the workhorse of the staff, Cummings finished the year with a 35-12 record, a 1.60 ERA, and league-leading totals for both shutouts (7) and strikeouts (82). Cummings' career included time in both the American Association and National League, and he also briefly served as the first president of the newly formed International Association (minor league) in 1876. The photo, which exhibits outstanding clarity, displays a few minor surface blemishes to some of the player images, but Cummings' image is free of any flaws. The mount (4.25 x 2.5 inches) displays light corner wear. (Any visible scratches are on the PSA holder.) This is a stellar representation of this great rarity! Reserve $5,000. Estimate (open).
