The National Gallery of Art previewed the largest ever Art Nouveau exhibition with a black-tie dinner in October. The Art Nouveau designers sought to create a complete decorative style that combined all of the arts, including painting, graphics, sculpture, decorative arts, and architecture, in a single, expressive whole. The exhibition features more than 350 stunning objects from 22 countries and includes works by Gustav Klimt,William Morris, Louis Sullivan, Louis Comfort Tiffany, and Frank Lloyd Wright. Guests also enjoyed music by composers from the Art Nouveau period, including Debussy and Ravel.
