Hall of Famer Fergie Jenkins spent 18 years in the MLB. He played for the Boston Red Sox from 1976-77. This size 7 1/2 Roman Pro Red Sox cap has been signed by Jenkins on the underside of the brim for player attribution. Jenkins autograph rates a 5 in our opinion. This cap has the appropriate tagging, has been presented to us as game-used and in our opinion shows excellent wear. Accompanied by an ALOA from JSA and documentation from MEARS.
