A 10-metre high sculpture of a man's buttocks is part of an art exhibition that has been shortlisted for the prestigious Turner Prize.
Anthea Hamilton is one of four artists nominated, receiving a nod for her solo show Lichen! Libido! Chastity! at SculptureCentre in New York, which features two hands clutching the bare bottom, as well as a brick-printed suit.
The other artists on the shortlist are Michael Dean, Helen Marten and photographer Josephine Pryde, whose installation Thinking By the person i Am at CCA Wattis in San Francisco includes a small working train.
The Turner Prize will return to London's Tate Britain with an exhibition of work by the four shortlisted artists ahead of the awards ceremony in December, which will be broadcast live on the BBC.
Mr Dean, who works primarily in sculpture, is nominated for his solo exhibitions Sic Glyphs at South London Gallery and Qualities Of Violence at de Appel arts centre, Amsterdam, and reference the everyday urban environment, such as the corrugated metal of a shop shutter.
Ms Marten is nominated for projects including Lunar Nibs at the 56th Venice Biennale and the solo exhibition Eucalyptus Let Us In at Greene Naftali in New York.
Her work uses found objects and crafted elements in sculptures and painting-like tableaux.
The winner of the Turner Prize will collect £25,000, with the other shortlisted artists receiving £5,000 each.
The award was established in 1984 and is awarded to a British artist under 50 for an outstanding exhibition or other presentation of their work.
The exhibition of work by the four shortlisted artists will be at Tate Britain from September 27 to January 8 2017.
