Six-time All Star shortstop Bert "Campy" Campaneris wore this A's flannel uniform vest during the 1966 baseball season with the Kansas City Athletics. In 1965, Campy had become the first player in history to play all nine field positions during the course of a major league game, and also led the American League in stolen bases for the first time (he did it six times in his career). Campareris' number 19 appears on the front and back; McAuliffe size 40 tag and "66" year tag on left front tail. Small stain on front below the A's logo; all trim and buttons intact and all original.
