Obtained in an auction of Hollywood Memorabilia from Profiles in History in Beverly Hills, California, this pen and ink set design drawing measures 4.75 by 9.5 inches. The drawing is on tracing paper(?) and is in fine condition. The image depicts a scene at the beginning of the movie with Wadsworth's car approaching the mansion.
The origin and authenticity of this drawing is unknown, but comes from a very reputable collector of Hollywood memorabilia. It is very similar to the storyboard sketch shown in the American Cinematographer Magazine (and featured on the index page of the website).
