6 April31 July 2005. Known for his bizarre and challenging work, Belgium's famous Surrealist, Ren Magritte, is now under the lens at Vienna's Kunstforum. The exhibition presents the artists entire collection, with images from the 1920s through to the 1960s, showing not only his Dada influences but also how his work inspired Pop and Concept Art in the after war years. Key works from international museums and several private collections show the artist from new angles, and visitors can enjoy surrealist versions of classic paintings as well as works that challenge our everyday perceptions. My painting is visible images which conceal nothing, declared Ren Magritte, they evoke mystery and, indeed, when one sees one of my pictures, one asks oneself this simple question 'What does that mean'? Admission: 8.70; concessions 7.30; children 4.40. 10.00 19.00 (until 21.00 Fri).
