The Steel Curtain made Sundays pure hell for opposing quarterbacks. The opposition knew that for about a three hour period, it would be under constant duress because the Steelers kept coming at you. This Riddell full-size replica helmet features the signatures of the “Steel Curtain” defense. Dwight White, Ernie Holmes, Mean Joe Greene and L.C. Greenwood all signed the exterior in gold paint pen. All of the signatures rate “10”.
