Collectible Rare Vintage Pittsburgh Steelers 1973 Helmet Radio and 1970’s gum-ball helmet. The radio helmet is in great condition though the radio doesn’t work. Probably could attach a new 9Volt adapter. I have the old one in photo. 1970’s collectible gum-ball helmet. 1 inch in size. A few scratches as shown. If you are a Steelers fan, this is for you!
