The vintage Official American League (Cronin) Ball is signed on the sweet spot by Mickey Mantle and on the side panel by Bobby Richardson. Both players have signed the ball in black ball point ink. The Mantle signature rates a 7.5 out of 10 due to some minor fading of the ink. The Bobby Richardson signature gets the same rating, again for minor fading. The ball does have some slight toning concurrent with its age, but what a great vintage signed ball this is.
