Translated from Dutch NOS TV today:
“In the painting one can clearly see the influence of Piet Mondrian, with whom Van Doesburg after settling in Paris in October 1923 interacted intensively for a short period. …
Meta Knol, director of the Leiden museum, is very happy with the purchase. From 1916 to 1921 Van Doesburg lived in Leiden. He developed his avant-garde art there and founded the magazine De Stijl, for which the art movement is named.
Until now only five abstract paintings by Van Doesburg from the 1920s could be seen in Dutch museums. Many paintings from that time were sold by his widow in the 1940s to museums and collectors in the United States. Contra-Composition VII was one of them.
The painting is 45.5 by 45.5cm.
