The silkscreen print depicts the legendary musician in a pose from his 1960 Western movie "Flaming Star."
An Andy Warhol painting of Elvis Presley — the artist's only full-length portrait — is for sale with an estimated price tag of $30 million.
"Double Elvis (Ferus Type)" depicts the hip-swivelling musician holding a revolver, as he appeared in the 1960 Western "Flaming Star."
The 1963 black-on-silver portrait is being auctioned by Christie's in New York on May 17, alongside Warhol's "Most Wanted Men No. 11, John Joseph H, Jr."
One of a series of mug shot images created by Warhol for the 1964 New York World's Fair, it's also expected to fetch $30 million.
The portraits are on display at Christie's London showroom from Friday until Tuesday.
Christie's contemporary art chairman Alex Rotter says the paintings are "very memorable and early examples of Warhol's profound understanding of fame."
