Communist Revolution in 1949, and now is a ballroom and disco. In the 1930s Italian architects built a small movie palace, the Cinema Impero, in Asmara in what is now Eritrea. Today, many of the movie theatres have been subdivided into multiplexes, but others have been restored and are used as cultural centres in their communities. Streamline Moderne In the late 1930s, a new variety of Art Deco architecture became common; it was called Streamline Moderne or simply Streamline, or, in France, the Style Paquebot, or Ocean Liner style. Buildings in the style had rounded corners and long horizontal lines; they were built of reinforced concrete, and were almost always white; and they sometimes had nautical features, such as railings and portholes that resembled those on a ship. The rounded corner was not entirely new; it had appeared in Berlin in 1923 in the Mossehaus by Erich Mendelsohn, and later in the Hoover Building, an industrial complex in the London suburb of Perivale. In the United States, it became most closely associated with transport; Streamline moderne was rare in office buildings, but was often used for bus stations and airport terminals, such as the terminal at La Guardia airport in New York City that handled the first transatlantic flights, via the PanAm Clipper flying boats; and in roadside architecture, such as gas stations and diners. In the late 1930s a series of diners, modelled upon streamlined railroad cars, were produced and installed in towns in New England; at least two examples still remain and are now registered historic buildings. Decoration and motifs Decoration in the Art Deco period went through several distinct phases. Between 1910 and 1920, as Art Nouveau was exhausted, design styles saw a return to tradition, particularly in the work of Paul Iribe. In 1912 André Vera published an essay in the magazine L'Art Décoratif calling for a return to the craftsmanship and materials of earlier centuries, and using a new repertoire of forms taken from nature, particularly baskets and garlands of fruit and flowers. A second tendency of Art Deco, also from 1910 to 1920, was inspired by the bright colours of the artistic movement known as the Fauves and by the colourful costumes and sets of the Ballets Russes. This style was often expressed with exotic materials such as sharkskin, mother of pearl, ivory, tinted leather, lacquered and painted wood, and decorative inlays on furniture
