The roaring years, or creativity in all its states.
The madness of the 1920s is characterized by many novelties, like the appearance of jazz, radio, cinema or home appliances. In Paris, the Montparnasse district symbolizes this renewal, where pleasure and exuberance are erected in a way of life. It’s the time of Josephine Baker, Art Deco, creations of Coco Chanel, etc. Conquered by this wave of creative and liberating euphoria, many Americans took advantage of this friendly and resolutely modern atmosphere before returning to a country prey to prohibition and conservatism.
