Prior to the release of the film, the studio would send out tidbits about production, marketing, and other information to a variety of people; from individual theatre owners to merchandisers to studio personnel. This is an original piece of legal-sized stationary that was usually the first page of any given correspondence, the remaining pages being standard onionskin or other plain paper.
I really like the minimal color scheme of red line art and black text. The line art itself is particularly engaging. In fact, some of this line art was reused in other places. The entire art is featured on the inside front cover of the National Screen Service Campaign Book, and some individual vignettes are used in the Whitman stationary set.
