Blank letterhead and envelopes, undated

Comprised primarily of Kimball's correspondence with Julius S. Held, one of the volume's editors, about the planning and production of the book. Held and Kimball also discussed at length a party to be held at the Metropolitan Museum of Art to celebrate Tietze's 70th birthday, which they later canceled because of concerns with Tietze's health. The sub-subseries also includes a small amount of correspondence with Tietze, the Gazette des Beaux Arts, and Alfred Barr of the Museum of Modern Art.
