A model train and bare buttocks are among artworks nominated for the prestigious Turner Prize.
Work by four shortlisted artists went on display Monday at London's Tate Britain gallery. The show includes Michael Dean's scrap-metal sculptures, Helen Marten's collage-based works, Josephine Pryde's model of a graffiti-covered train and Anthea Hamilton's surrealist sculptures, including a 10-meter (33-foot) tall model of a man's naked posterior.
The winner of the 25,000-pound ($32,000) prize will be announced Dec. 5.
Founded in 1984 and given annually to a Britain-based artist under 50, the prize often sparks heated debate about the value of modern art.
Named for 19th-century landscape painter J.M.W. Turner, the award helped make stars of potter Grayson Perry, shark pickler Damien Hirst and "12 Years a Slave" director Steve McQueen.
