This is one of Penrose's earliest compositions constructed from postcards. These innovative collages are the artist's most significant contribution to surrealist art. Collage had been frequently used by both cubist and surrealist artists, but it was a new idea to feature the repetitive use of the same image. The artist René Magritte, in particular, was an admirer of these works. Among the other materials used for this collage is a rubbing from a piece of wood. This has been used for the face of the female figure.
