"The Mary Sisler Collection was the most important private collection of works by Duchamp; and the exhibition, a historical event. It was the first and the most inclusive Duchamp retrospective to be held by a private gallery in the United States" (Schwarz). When Mary Sisler saw the first version of the catalogue she was incensed that her name was not only much smaller than Duchamp's, but at the bottom of the title-page, and demanded that the catalogue be withdrawn, and be reissued. As a result surviving copies of the first version are extremely rare. Both deluxe editions contain an original print by Niki Ekstrom of a photograph of Duchamp, and are from the original edition of 100, signed and numbered by Duchamp, who also boldly wrote his name in brown marker on the cover of the suppressed version, and put his signature and Mary Sisler's name in brown marker on the front cover of the replacement version. The first version comes from the collection of the publisher of the catalog, Arne Ekstrom, and is reproduced in Etant Donne No.10, p. 86. Schwarz, The Complete Work of Marcel Duchamp No. 616, for the second and third versions only.
