Ty Cobb and Larry Lajoie dual-signed William Harridge American League baseball. Cobb signed the side panel of this ball, and added "8/21/54" below his signature. Lajoie signed on a separate side panel, just below the "8/21/54."The ball is in very good to excellent condition, and the autographs rate 7/10 overall. Cobb finished his legendary career with 4,191 hits, and was inducted into the National Baseball Hall of Fame in 1936. Lajoie collected 3,252 hits during his career. He was inducted into the Hall of Fame a year after Cobb was inducted. Please note that they were great rivals in their era, including a notable contest for a free car to the winner of the batting title one year. Please note the lot includes a full LOA from PSA. This is an outstanding signed baseball, two of the first six inductees in the Hall of Fame paired together, a supremely rare and great baseball.
