A collector obtained the Library card several years ago from Bud Glass and Russ Howe, and it is that collector who is now offering the signed library card for sale in this auction. Background

Two longtime Elvis memorabilia collectors made the find of a lifetime: the oldest known complete Elvis signature. It was written on a checkout card from his school library when he was in seventh grade in Tupelo, Mississippi. The collectors, Bud Glass and Russ Howe, were introduced to a former librarian at the junior high in Tupelo through a mutual acquaintance. Glass has signed letters of authenticity from the former librarian, who found the card in the book "English Fairy Tales." The librarian, who got permission to search the school library for other cards after she found this one, put it in her scrapbook and kept it for over 40 years. The story is even more piquant because the wing of the Milam School in Tupelo that contained the old library burned in February 1979. If the librarian hadn't saved the signed card in her scrapbook, it would have gone up in smoke.
The next earliest complete Elvis signature is from when he was in high school in the early 1950's. Glass also located three people who had checked out the book at the same time as Elvis.
