Exceptionally rare helmet from this A.F.L. squad is one of the most desirable styles on the face of the earth. Any serious football collector should be absolutely drooling over this gorgeous specimen, showing use but metric tons of appeal. Great Lone Star State design on sides on this surprisingly low-tech headgear with "RK4 Helmet" sticker inside below the suspension straps. "Riddell" stamped on face mask. It's just impossible to overstate the desirability of this piece. Unbelievable!
