Mort Cooper was the ace of the St. Louis Cardinals' pitching staff when they appeared in three straight World Series in 1942, 1943 and 1944. During those years, he won a combined 65 games (most in the Major Leagues) and was the 1942 NL MVP and a four-time All-Star. He used this glove throughout his career. The glove originally came from the Cooper family and "Cooper" is written in black on the pinky.
