When he exhibited a urinal at the Society of Independent Artists exhibition in 1917, Marcel Duchamp's revolutionary gesture was to reimagine the everyday world as a source of readymade objects for the artist, thus shifting the focus of art-making from a craft practice to an intellectual activity. The everyday object became art because it was chosen to be so by the artist. But these transactions between life and art don't only flow in one direction. The everyday world -- and particularly the advertising industry -- frequently uses art as a source of readymades for its own less highbrow business.

Why buy portrait when you can afford landscape indeed? Nice.
