The subseries contains transparencies, slides, and glass plate and film negatives primarily of works of art by Marcel Duchamp. Of particular interest is a glass plate negative of the cast shadows of several of Duchamp's Readymades. The subseries also includes three portraits of Duchamp, including one with his head shaved in the form of a comet and marked "Voici Rrose Sélavy." There is also a negative of Roche's view of Duchamp's 33 W. 67th Street studio with the "Traveller's Folding Item" in foreground.
Subseries B. Negatives and transparencies
Negatives and transparencies of Duchamp's works of art are filed first, and alphabetically by title of the work. Snapshots and portraits are filed last, and alphabetically by photographer, and then title/subject.
