In 1972 the already famous curator Harald Szeemann invited Howard Kanovitz--together with the Americans Chuck Close and Richard Estes, the British painter Malcolm Morley, the Swiss artist Franz Gertsch and the Germans Gerhard Richter and Sigmar Polke--to take part in the documenta 5 exhibition in Kassel as exponents of photography-based painting. Kanovitz also participated in documenta 6 in 1977. He was given solo shows by museums in other cities, including Utrecht, Duisburg, Berlin and Hannover. Visible Difference at the Ludwig Museum, Koblenz, is Kanovitz's first solo exhibition in a museum since 1980. It offers an opportunity to rediscover this master of Pop Art and Photorealism, to trace his artistic development through seminal works from his oeuvre, and to conduct a scholarly exploration of his artistic significance in retrospect.
