Boîte-en-valise (de ou par Marcel Duchamp ou Rrose Sélavy) by Marcel Duchamp is a box covered in linen that contains sixty eight miniature replicas and reproductions of works by the artist. The box measures roughly fifteen inches by sixteen inches by three and a half inches when closed. When displayed, different pieces are able to be seen. Some examples of works within the box include: Nude Descending a Staircase, Paris Air, Underwood, and Fountain. When the box is opened, the frame forms a letter “M” for the artist’s name. The main structure of the frame contains five rectangular sections. Four of them are equal in dimensions while the last is tall and narrow. Within the frames of the four equal sections are four distinct 2-D reproductions. They are all abstractions. The tall and narrow section to the left contains three small replicas of sculptures. One is a small glass vial with a hook, a black pouch, and a urinal. The reproduction of Nude Descending a Staircase, which is an abstraction of skin-colored lines and rectangles, is housed within a book or portfolio and when on display, the book is opened and sits upright. The remaining reproductions lay on the cushioned interior of the box’s cover. One of the pieces is L.H.O.O.Q, which is a postcard of the Mona Lisa but with a moustache painted on her face.
