Bill “Billy” North 1972 Chicago Cubs Home Jersey. 1972 was the first season the Cubs abandoned the long-standing wool flannel full-button front jerseys and switched to the polyester pullover double-knits, which was a wave that swept through the MLB in the early 1970’s. The stitching outline around the strip tag remains visible. Shows outstanding usage and is stunning to see in person. Comes with an LOA from Ball Park Heroes. The Stigall brothers at Ball Park Heroes are widely respected in the game-used space.
