Oklahoma State Cowboys Riddell Revolution helmet from the 2011 season.  The rare helmet is a size large and was only worn during the 2011 season for three (3) games and never worn again in the matte gray with that logo.  The helmet is complete and original, and was worn by #64 as indicated by the written player identfier numbers on the interior and the player identifier #4 on the rear right side of the helmet.  The helmet is missing the opposite side #6, the front and rear bumper decals, and the American Flag decal from the rear of the helmet - all removed by the team prior to the helmet's release.
