Awesome Baltimore Colts full-size helmet. Autographed and inscribed by John Mackey, Hall of Famer number 88. The helmet is in above average physical condition. It still has the original Rydell tags on it, but it is a bit dirty from being on display, and there are a few scuffs on the helmet. See pictures. The autograph has begun to fade from time. This helmet was displayed in the open, so dust and dirt has covered the autograph and inscription. We have not tried to clean it. This autograph was done at a Steiner sports convention in the late 90s , the Steiner sports COA sticker is on the back of the helmet, however the certificate is lost. Please see pictures and bid accordingly. We will guarantee this items authenticity, it will pass any professional authentication.
