A masterpiece of modernist art that has been in the collection of the Philadelphia Museum of Art for almost 70 years has been characterized as “Nazi-looted art” by representatives of the artist’s heirs who plan to challenge museum ownership in court, although the artist never objected during his lifetime.The painting, Composition with Blue, a 1926 work by Dutch artist Piet Mondrian, was purchased in 1939 by famed collector A.E. Gallatin, who acquired it from the Buchholz Gallery in New York, a sales outlet favored by the Nazis.(English)
