Curley Culp personally autographed a Houston Oilers Riddell mini helmet with HOF 13 inscription. A member of the Kansas City Chiefs from 1968-1975 before being traded to the Houston Oilers and playing there until 1980. At nose tackle his strength often required double teams which freed up holes for linebackers. This includes a picture from the signing as well as a certificate of authenticity from James Spence Authentication (JSA) with matching serial numbered tamper proof hologram.
