When I was in the first grade, my father broke his back while at work and lost the use of his legs. After he got out of the hospital he adopted the hobby of writing to celebrities and asking for autographs. He amassed over 60,000 signed photos and other memorabilia before his health took his hobby away from him, a few years before he passed away. The signed photo in this listing is part of his collection. Due to the nature of how the signature was obtained through the mail, Authenticity cannot be guaranteed.
