Signed on the sweet spot of a Harridge Official OAL baseball. Artfully added is the provenance that this was given out at the famed Hal "Bud" Binyon's restaurant in Chicago. It was a gathering spot for some of Chicago's power brokers. This was a celebration for Mack's Hollywood debut as they were going to put him in the movies at 91. Ralph Gutgsell who was Mack's cousin got this as a party favor. There was likely a single signed ball sitting at each quest's place. We have never seen another! EX-MT JSA LOA.
