This work was conceived as the cover for the catalogue of a surrealist exhibition held in Paris in 1947. The exhibition, organised by André Breton and Duchamp, was to mark the return of Surrealism as a force in Europe after the war. Produced in an edition of 999 de-luxe copies, the cover of the book has a breast made of foam rubber. Duchamp originally tried to cast the left breast of the artist Maria Martins, but this proved too complicated. So, with characteristic ingenuity, Duchamp bought 999 false breasts and got his friend, the artist Enrico Donati, to help him glue them to the book-covers and hand-colour the nipples. The breast sits on a velvet backing, attached to the pink cover. The book features original prints by Tanguy, Tanning, Brauner, Ernst, Miró, Bellmer, Arp and others.
