Is Amsterdam’s Stedelijk Museum in danger of losing its important collection of 14 Malevich paintings? “The heirs of the Russian avant-garde artist, who have successfully claimed works from the Museum of Modern Art in New York and the Busch-Reisinger Museum of Harvard University, are now in pursuit of a significant part of the largest collection of Malevich’s works in the West. They say that the Stedelijk bought the works from someone who didn’t own them and had no right to sell them.”
