'Duchamp, Man Ray, Picabia' at Tate Modern, London, Britain - 19 Feb 2008
The iconic 'Fountain' (1917) by Marcel Duchamp (1887-1968) - the public urinal that Duchamp transformed into a work of art and is seen as the paradigm of the 'readymade' - a conscious effort to break every rule of the artistic tradition and create a new kind of art.
