J.C. Martin Autograph On Paper Good. The autograph has not been authenticated, however I know it is real because I got it from J.C. Martin in 1971. Henry's was a local fast food chain in the Chicago suburbs. He had a signing event near my house and I went and got the autograph. There are no rips, tears or other writing besides his signature. You can see there are tape marks on the top and bottom from when I put it in a scrapbook.
