A decorative style popular in the United States and Europe during the 1920s and 30s, Art Deco stems from a style popularized by the Exposition Internationale des Arts Decoratifs et Industriels Modernes held in Paris in 1925. A term not used at the time, "Art Deco" only became popular during a period of styalistic revival during the 1960s. A widely applied term it is most specifically French in origin and implementation, although American architecture of the period borrowed heavily from the specific styles.
The style is dynamic and modern and owes much to the decorative arts of turn of the century Vienna. The Oxford Dictionary of Art notes that “the Art Deco movement encompassed a wide variety of decorative arts that were characterized by a certain sensuousness of curving forms, a lavish employment of luxurious materials and bold combinations of colors and floral patterns” (Tise). This style has been applied to everything from jewelry to skyscrapers and has come to stand for the golden age that occurred before the Great Depression.
