The style originated in the 1920s and continued to be employed until after World War II. The term "art deco" first saw wide use after an exhibition in 1966, referring to the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes that was the culmination of high-end style modern in Paris. Led by the best designers in the decorative arts such as fashion, and interior design, Art Deco affected all areas of design throughout the 1920s and 1930s, including architecture and industrial design, as well as the visual arts such as painting, the graphic arts and film. At the time, this style was seen as elegant, glamorous, functional and modern.   -  See also: Art Deco or more info on styles Style specifics: Abstract motives and geometrical forms are quite typical for the Art Deco period.
