Apolinère Enameled

Apolinère Enameled was painted in 1916–17 by Marcel Duchamp, as a heavily altered version of an advertisement for paint ("Sapolin Enamel"). The picture depicts a girl painting a bed-frame with white enamelled paint. The depiction of the frame deliberately includes conflicting perspective lines, to produce an impossible object. To emphasise the deliberate impossibility of the shape, a piece of the frame is missing. The piece is sometimes referred to as Duchamp's "impossible bed" painting.

Apolinère is a play-on-words referencing the poet, writer and art critic Guillaume Apollinaire, a close associate of Duchamp during the Cubist adventure. Apollinaire wrote about Duchamp (and others) in his book The Cubist Painters, Aesthetic Meditations of 1913.
