Recently I purchased a Bart Starr signed full size helmet off Ebay. I know there's a lot of concern with buying auto's off Ebay. The helmet came with a Steiner authentication, but there's no code on the sticker to verify the authentication. I wanted anyone's thoughts on the autograph. I have posted the auto to this discussion. The Steiner sticker does not look tampered with, but I'm still hesitant to trust the authentication. Thanks to anyone who has any thoughts!
