Here's one that comes from the dusty archives of the Chicago Public Library's film collection. Titled simply Chicago Is..., this film 1977 sought to lure travelers to Chicago during a period of transition for what was, at the time, the county's second largest city. The film comes as a collaboration between the Chicago Convention & Tourism Bureau, the United States Travel Service and the Illinois Office of Tourism — the latter two which are now known as the U.S. Department of Commerce and the Illinois Department of Business and Economic Development. Chicago is marketed as a city that not only has a skyline with sensational skyscrapers, but it's also a city of museums and many outdoor attractions, specifically the lakefront and the many outdoor plazas that stood at the base of Loop office towers. There's even a clip of the old Great America theme park, well before the days of Six Flags. The film certainly makes Chicago look like a really swell place.
