The King's briefs are to go on sale at an auction of Elvis Presley pop memorabilia.
Unwashed and still soiled with stains, the pair of Presley's underpants was worn beneath one of his famous white jumpsuit's during a performance in 1977.
The light-blue dance briefs are expected to fetch up to £10,000 when they go under the hammer next month at the auction in Stockport, Cheshire.
Elvis did not want any lines visible while he was on stage wearing his vast array of dazzling jumpsuits and this pair of underpants was obtained from the estate of Vernon Presley, Elvis' father.
Presley died 35 years ago this month and there is expected to be a lot of interest from his fans from across the globe.
Other items up for sale include his personal Holy Bible, which is expected to raise up to £25,000.
The bible was given to Presley on his first Christmas at Graceland in 1957 and used throughout his life until his death on August 16 1977.
It contains his handwritten notes, thoughts, annotations and underlining throughout.
Poignantly, one of the many lines emphasised by the entertainer states: 'What is a man advantaged if he gain the whole world and lose himself or be cast away.'
Also on sale is 16mm film footage taken from Priscilla Presley's own personal home movies of Elvis, especially of vacations and their daughter Lisa growing up.
It also includes footage of their wedding and the very first time Elvis and Priscilla brought their daughter home to Graceland from the hospital, Christmas inside Graceland and other special family moments.
