Grabbed from Sports Illustrated, 1983
I've never seen a White Sox jacket like this- perhaps Mr. Einhorn had it commissioned for himself? Eddie Einhorn, who is still part owner of the Sox, made his fortune in syndicating college basketball in the Fifties and Sixties and later became the head of CBS Sports.
I dig how the stripes echo but do not copy the horizontal stripes of the early Eighties White Sox uniforms. I'm sure this thing was 100% polyester.
