These days airlines try to appeal to customers by offering them chocolate chip cookies or a free checked bag. Back in the day airlines tried a little harder. They created advertisements that could easily be mistaken as works of art.
Author Matthais C. Hühne has put together an awesome collection of vintage airline ads for his book,, Airline Visual Identitty: 1845-1975. The book provides unique insight into the design and advertising methods of an era when airlines were considered the most glamorous form of travel.
