An Andy Warhol portrait of Elvis Presley is expected to fetch upwards of $30 million when it hits the auction block this spring.

The silver silkscreen painting is to go under the hammer at auction house Sotheby's in New York City on May 9.

The painting, dubbed Double Elvis (Ferus Type), depicts the King as a cowboy, shooting a gun with a holster on his hip. A second image of Presley, which appears vaguely like a shadow, can also be seen in the background.

The work of art was previously displayed at the Ferus Gallery in Los Angeles.

It is currently owned by a private collector.
