I love this work. There feels to be Munch in it. Kupka (1871-1957) was an artist from Czechoslovakia. More below.
Kupka was supported by Jindrich Waldes, who collected his work. Waldes’ collection was confiscated first by the Nazis, who deemed abstraction decadent, and later by the Communists, who declared his work “an example of imperialist ideology and cosmopolitan nihilism that is harmful to the people.” The Communists took 300 of Kupka’s works from Walles to hang in the National Gallery. Most were returned to the Waldes family, but not the major ones, until 1997.
