The basic theme of this exhibition is perceptual phenomena, which can be found in the works of all three artists, albeit in very different ways. Cécile Hummel is interested in surreal effects, which she depicts using traditional drawings. While the whole of her world can only be seen in the details, Leopold Schropp juxtaposes the diversity of extracts with a sculpture. It preserves a unity of details. Mario Sala shows the slipping away of the world by feigning its reliability. He has installed a solid sheet metal tube at eye level and connected it with pictures.
