For the first time the two New York based visual artists Mary Heilmann (b. 1940 in San Francisco) and David Reed (b. 1946 in San Diego) present their expressive and intensely colourful works in the form of a dialogue in the specially designed joint exhibition "Two By Two" at Hamburger Bahnhof –   Museum für Gegenwart –   Berlin. The art works shown span the four decades since the seventies. As the title "Two By Two" already suggests, the central focus of the exhibition is formed by nineteen pairs of images, which show the works in unusual mutual proximity. In this symbiosis they can no longer be viewed separately from each other, but merge with the viewer’s imagination in a new way.
