The Public Information and Advertising Department series includes advertising literature, newsclippings, trade catalogs, correspondence of department managers, technical reports, blueprints, engineering correspondence and press releases. The files also include biographical material on Elmer Sperry and an oral interview with Hannibal Ford of the Ford Instrument Co. Other files document Sperry's efforts to work with the military during World War II to produce a series of films for defense. Of particular interest are papers describing the company's efforts to help produce the motion pictures "The House on 92nd Street" and "The Road to Murmansk."
