A huge sculpture of buttocks, more than £20,000 in pennies and a "brick suit" are among the artworks at this year's Turner Prize exhibition.
The winner of the controversial contemporary art prize, now in its 32nd year, will be announced in December.
Work by the four shortlisted artists competing for the £25,000 award is on show at Tate Britain, in an exhibition which opens on Tuesday.
They include Anthea Hamilton's giant sculpture of a backside, entitled Project For A Door (After Gaetano Pesce) 2016.
Measuring around 16ft high, the piece is part of a series of "physical realisations" of images taken from the artist's archive.
"While rooted in the history of sculpture, her work engages the viewer by her humour and unexpected combinations of images, materials and words, as well as dramatic shifts in scale," Tate said.
Anthea's work also consists of a "brick suit" - a fabric suit which is camouflaged against the wall behind.
Fellow artist Michael Dean's work includes a sculpture consisting of £20,435.99 in pennies, representing "one penny below the UK poverty line for a family of four".
A model of a train entitled The New Media Express In A Temporary Siding (Baby Wants To Ride) 2016 has been installed by artist Josephine Pryde.
Helen Marten's work features handmade as well as found objects such as cotton buds and fish skins to create "poetic visual puzzles".
Turner Prize 2016 runs until January 2 2017 at Tate Britain.
The prize will be presented at Ferens Art Gallery in Hull as part of the UK City of Culture celebrations on December 5.
