An Andy Warhol painting of Elvis Presley – the pop artist’s only full-length portrait – is for sale with an estimated price tag of around US$30 million (A$39 million).

‘Double Elvis (Ferus Type)’ depicts the hip-swivelling musician holding a revolver, as he appeared in the 1960 western movie Flaming Star. A ghostly duplicate image hovers in the background.

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.

The portraits are on display at Christie’s London showroom from Friday until Tuesday.

Christie’s contemporary art chairman Alex Rotter said the paintings – of “the King of Rock ‘n’ Roll and the career criminal” – are “very memorable and early examples of Warhol’s profound understanding of fame”.

The record for a Warhol work is US$105 million (A$136 million) paid for ‘Silver Car Crash (Double Disaster)’ at a 2013 Sotheby’s auction.
