This is No. 1 of a ‘de luxe’ edition of a travelling case (by Louis Vuitton) assembling 69 reproductions of Duchamp’s own work. This edition has one ‘original’ and a dedication to Peggy Guggenheim, who assisted Duchamp financially in its production. It includes a miniature of the celebrated upturned urinal, Fountain of 1917, and a reproduction of a ‘corrected ready-made’ of 1919—Leonardo da Vinci’s Mona Lisa, hirsute and inscribed ‘L.H.O.O.Q.’ These letters, when pronounced in French, make the phrase ‘Elle a chaud au cul’, which was decorously translated by Duchamp as ‘there is fire down below’.
