The publicity records contain output of the public relations arm of the 1940 Golden Gate International Exposition. The records document the activities of the exposition and the promotional effort required of the exposition's public relations department. The public relations documents comprise the bulk of the records and are newspaper, magazine, and radio press releases, typescript mimeographed. The public relations documents concern the 1940 exposition, but one file of background information on the 1939 exposition is also present. The publicity materials include one folder of a series of forty-five feature stories, typescript mimeographed, by the California editor and writer Jack Cook, presenting a daily tour of the exposition's exhibits.
