On April 9, you’ll be able to get into museums with he password “R. Mutt” or “Richard Mutt” at the admissions desk between 3 and 4PM. Artnet has the full details, including the confirmed institutions that are participating. R. Mutt, of course, refers to the pseudonym that artist Marcel Duchamp used to sign his 1917 work Fountain, a porcelain urinal that became Duchamp’s most famous “readymade” — a commonplace, manufactured object appointed as art. A conceptual art movement was born. This year is the centennial of Fountain. We’re celebrating with a few of Duchamp’s words of wisdom about being an artist.
