 Marcel Duchamp is thought to have perfected the concept several years later when he made a series of ready-mades, consisting of completely unaltered everyday objects selected by Duchamp and designated as art.The most famous example is "Fountain" (1917), a standard urinal purchased from a hardware store and displayed on a pedestal, resting on its side.In its strictest sense the term "ready-made" is applied exclusively to works produced by Marcel Duchamp, who borrowed the term from the clothing industry () while living in New York, and especially to works dating from 1913 to 1921.
