Art Deco was an influential design style that emerged after World War I, characterized by geometric shapes, bold colors, and lavish ornamentation. It represented luxury, modernism, and faith in social and technological progress. Many buildings from the 1930s-1940s have an Art Deco exterior with symmetrical designs, distinctive windows and colors. Identifying characteristics of Art Deco architecture include rounded corners, horizontal banding, columns, glass blocks, and zigzag or stepped designs. Materials often included stucco, concrete, stone, and terra cotta. Windows were usually arranged in continuous horizontal bands. Prominent Art Deco buildings included the Chrysler Building, Empire State Building, and Radio City Music Hall.
