Elvis' library card

The King would have signed his own name a million time sover throughout his career, but this particular signature - up for auction next week - was peened well before his fame.

The card dates all the way back to 1948 when a thirteen year old Elvis Presley checked out a copy of The Courageous Heart: A Life of Andrew Jackson For Young Readers from Humes High School in Memphis soon after his family had relocated there.

The card was found by a very lucky librarian while in the middle of throwing out old books. It's thought to be one of the older signatures Elvis ever penned and is expected to sell for over

The 1948 card was found by a librarian while throwing out old books.

The card, which is being sold along with a copy of the book, is expected to fetch more than $3,600 when it goes to auction on August 14.

Other items in the Heritage Auctions Ultimate Elvis Signature Auction include guns, pill bottles and a trnch coat belonging to the legend who died in 1977.
