Herschel Walker Autographed (authentic, not mass produced) Mini Helmet. Herschel Walker played college football at the University of Georgia and won the Heisman Trophy in 1982. He played in the NFL for the Dallas Cowboys, Minnesota Vikings, Philadelphia Eagles and the New York Giants. The helmet was signed in Vancouver BC at a dinner in which Herschel Walker was the guest speaker, and I was there in person when he signed it. Outstanding memorabilia piece for the vintage football collector. Reduced to $60
