"Using the Mona Lisa to mediate between high and low culture is not new. Soon after the turn of the 20th century, the Dada movement revolted against the "high cultural" content of the visual arts. In doing this, in some cases the Dadaists elevated the mundane into the world of the "aesthetic" by forcing observers to look at everyday objects in surprisingly new contexts. At other times cherished objects and symbols were ridiculed. The most well known act of degrading a famous work of art is probably Marcel Duchamp's L.H.O.O.Q., a cheap postcard-sized reproduction of the Mona Lisa upon which in 1919 the artist drew a mustache and a thin goatee beard."
