1957 New York Yankees team-signed ball hosts 26 autographs from the American League champions. Official American League (Harridge) ball has a terrific look and features Yogi Berra on the sweet spot. (The signature of Mickey Mantle on the sweet spot has been deemed a clubhouse example by PSA.) Also present are: Bobby Shantz, Sal Maglie, Don Larsen, Tony Kubek, Bill (Moose) Skowron, and more. Two notes: the year 1957 is written on the blue stamping in unknown hand, and the Reach stamp on the side panel has a handwritten number 39, indicating this ball was signed for catcher Darrell Johnson (his uniform number was 39), whose signature also appears. Ball has a nice appearance with moderate toning, stamps are clear, autos average 6-7/10. Comes with PSA LOA.
