All of the autographs in this category have been obtained by me TTM (Through the Mail). I've collected TTM autographs for 40+ years and all of the autographs are authentic to the best of my knowledge. Whenever I've received an autograph that may have been ghost signed, I've thrown them away. I guarantee all of the autographs that I sell to be authentic. If a purchased autograph is deemed not to be authentic, the purchase price will be returned upon returning the autograph.
