Lists of works included and not included in the "Box." Includes draft of letter to unknown recipient regarding Nicolas Calas article and gift of Katherine Dreier's collection to the Philadelphia Museum of Art, late 1940s-early 1950s?

A small subseries documenting limited aspects of Duchamp's planning and implementation of the "Box" in which he reproduced in miniature 69 of his works of art. The deluxe edition, known as the "Box in a Valise," also included an original work of art. Most of the material included here seems to pertain to Duchamp's production and management of the collotype reproductions for the "Box." There are inventories of Box supplies, as well as a diagram of their location within Duchamp's studio and what appears to be a list of related expenses. There are also lists of "Box" and "Box in a Valise" owners, part of a letter from Walter Arensberg listing the works by Duchamp he owned, and chronologies of Duchamp's career.
