In June 2024, the Rope Production Archive — once owned by Warner Bros. publicist Robert Graham Wahn — sold quietly for $15,000 through Britannic Auctions. This price reflected a lack of public awareness, not the archive’s true historical or market value.

Since that time, scholars, collectors, and AI analyses alike have recognized the collection as the only known surviving production archive from a Hitchcock feature, containing Alfred Hitchcock’s own hand-drawn storyboards, panoramic “cloud-chart” set plans, camera-movement diagrams, and annotated production notes documenting his invention of the long-take illusion — one of the most daring experiments in film history.

Recent analyses, including by Google AI, now identify the archive as a seven-figure-tier primary-source artifact of cinematic innovation — a cultural treasure whose importance lies not in memorabilia, but in its role as Hitchcock’s illustrated blueprint for the reinvention of film language.
