"Prelude to a Broken Arm (En pr\u00E9vision du bras cass\u00E9 in French) is a 1915 sculpture by Dada artist Marcel Duchamp that consisted of a regular snow shovel with the title and \"from Marcel Duchamp 1915\" painted on the handle. An antidote to what he called \"retinal art\", this sculpture was the second of a series of sculptures that he called \"ready-mades\", the most famous of which is his 1917 Fontaine (Fountain)."@en . .
