This rare two-volume publication by Arturo Schwarz offers an exhaustive scholarly examination of Marcel Duchamp's monumental work *The Large Glass* and its related pieces, bearing the distinguished signatures of both the artist and author as copy 117 of 135 in pencil on the colophon. One of 95 copies issued without the additional suite on vellum, the set was published by Galleria Schwarz in Milan and presented in original paper covers with elegant white fabric-covered boards, a printed spine, and a Plexiglas slipcase. This meticulously produced limited edition stands as both a significant art historical document and a collectible artifact in its own right.
