Art Deco style was established on the ashes of a disappeared world, the one from before the First World War, and on the foundation stone of a world yet to become, opened to the most undisclosed promises. Forgetting herself in the whirl of Jazz Age and the euphoria of the “Années Folles”, the Garçonne with her linear shape reflects the architectural style of Art Deco: to the rounded curves succeed the simple and plain androgynous straight line... Architecture, painting, furniture and sculpture, dissected by the author, proclaim the druthers for sharp lines and broken angles. Although ephemeral, this movement keeps on influencing contemporary design.
