New York baseball fans can not be better represented than in the legendary figure that is Casey Stengel - a player on the New York Giants and Brooklyn Dodgers, and a manager of the Dodgers, Yankees and Mets, this Hall of Famer signed in blue ink this rubber-centered, "wool felt" official "Special League" baseball.   Nicely worn, magisterial, and a preciously NR-MT; Stengel's autograph rates 8/10, and, despite a few brief breaks in line, holds together strong and regal.
