The 1948 library card with Elvis's signature was found by a librarian while discarding old books, is expected to fetch thousands when it goes up for auction next week, the 'Daily Mail' reported.

The card, which is being sold along with a copy of the book, is expected to fetch more than 2,500 British pound (USD 3,897) when it is sold on August 14.

The signature is thought to be one of the oldest ever autographs penned by the King, who died at the age of 42 in 1977.

Other items in the Heritage Auctions Ultimate Elvis Signature Auction, which will be held at The Peabody Hotel in Memphis, include guns and pill bottles belonging to the late star, as well as his trench coat.

"Elvis remains one of the most popular and durable figures in American Pop Culture," Director of Entertainment & Music Memorabilia at Heritage Auctions Margaret Barrett was quoted as saying by the paper.

In June a watch given by Elvis Presley to a friend while on military duty in the late 1950s has sold for over 32,000 British pound (USD 49,888) at auction.

Elvis gave the Omega Constellation to army friend Charlie Hodge and it was snapped up by a collector for more than five times its estimate.

Elvis started his career in Memphis after his family moved there from Tupelo when he was 13.

The singer went on to publish 13 number one albums and appear in 33 films, despite a brief break in his career when he was drafted in for military service in 1958.
