The Airport Hilton in St. Louis is a TWA shrine.
Pictures of happy movie stars climbing into TWA airplanes abound.
Every room has two or three...
I had an old friend, now passed away, who was one of the top photographers for TWA in the 50s and after. He was based at their corporate headquarters in the 50s and early 60s and then in Kansas City at the main office.
A lot of their famous advertising photos he created from that era. His collection of photographic and other art from that era was great.
