He played his entire 14-year Major League Baseball (MLB) career for the Boston Red Sox (1937-1951). A nine-time MLB All-Star, Doerr batted over .300 three times, drove in more than 100 runs six times and set Red Sox team records in several statistical categories despite missing one season due to military service during World War II. He was inducted into the Baseball Hall of Fame in 1986. The autograph on this card is distinct and well placed at the bottom of the card.
