The Klar Form exhibition was a non-figurative exhibition that was held in Kunstnernes Hus in 1952. The exhibition was organized by the French Madame Denise René and consisted of both paintings and sculptures René had brought with her from her gallery in Paris. René herself said that some of the art she had taken with her could seem unfamiliar to the Norwegian public, and she wanted it to come as a shock. All in all, you could see approximately 250 works of art by 19 artists.

The artists who were represented:
Arp, Taeuber-Arp, Bloc, Calder, Del Marle, Dewasne, Deyrolle, Dias, Domela, Herbi, R. Jacobsen, Lapique, le Corbusier, Léger, Magnelli, R. Mortensen, Pillet, Poliakoff, Raymond og Vasarely.
