Marcel Duchamp's ready-made urinal has been voted the most influential work of art of all time by 500 art experts. Pablo Picasso's "Les Demoiselles d'Avignon" and "Guernica" paintings must have felt a little peeved at missing out on the top spot to a toilet.

Duchamp's urinal tops art survey
Duchamp shocked the art establishment when he took the urinal, signed it and put it on display in 1917.
"The choice of Duchamp's Fountain as the most influential work of modern art ahead of works by Picasso and Matisse comes as a bit of a shock," said art expert Simon Wilson.
