polemical exhibition entitled Entartete Kunst (Degenerate art), in Munich; it subsequently travelled to eleven other cities in Germany and Austria. The show was intended as an official condemnation of modern art, and included over 650 paintings, sculptures, prints, and books from the collections of thirty two German museums. Expressionism, which had its origins in Germany, had the largest proportion of paintings represented. Simultaneously, and with much pageantry, the Nazis presented the Grosse deutsche Kunstausstellung (Great German art exhibition) at the palatial Haus der deutschen Kunst (House of German Art). This exhibition displayed the work of officially approved artists such as Arno Breker and Adolf Wissel. At the end of four months Entartete Kunst had attracted over two million visitors, nearly three and a half times the number that visited the nearby Grosse deutsche Kunstausstellung. Post-World War II art Post-war art trends in Germany can broadly be divided into Socialist realism in the DDR (communist East Germany), and in West Germany a variety of largely international movements including Neo-expressionism and Conceptualism. Notable socialist realism include or included Walter Womacka, Willi Sitte, Werner Tübke and Bernhard Heisig. Especially notable neo-expressionists include or included Georg Baselitz, Anselm Kiefer, Jörg Immendorff, A. R. Penck, Markus Lüpertz, Peter Robert Keil and Rainer Fetting. Other notable artists who work with traditional media or figurative imagery include Martin Kippenberger, Gerhard Richter, Sigmar Polke, and Neo Rauch. Leading German conceptual artists include or included Bernd and Hilla Becher, Hanne Darboven, Hans-Peter Feldmann, Hans Haacke, and Charlotte Posenenske. The Performance artist, sculptor, and theorist Joseph Beuys was perhaps the most influential German artist of the late 20th century. His main contribution to theory was the expansion of the Gesamtkunstwerk to include the whole of society, as expressed by his famous expression "Everyone is an artist". This expanded concept of art, known as social sculpture, defines everything that contributes creatively to society as artistic in nature. The form this took in his oeuvre varied from richly metaphoric, almost shamanistic performances based on his personal mythology (How to Explain Pictures to a Dead Hare, I Like America and America Likes Me) to more direct and utilitarian expressions, such as 7000 Oaks and his activities in the Green party. Famous for their happenings are HA Schult and Wolf Vostell. Wolf Vostell is also known for his early installations with television. His first installations with television the Cycle Black Room from 1958 was
