The non-Finnish collection reflects the international trends in vogue at the time the works were acquired by the Foundation. Informalism was the dominant trend in the European art of the 1960s. The major Informalist artists represented in the collection include Pierre Soulages, Antoni Tápies, Jean Dubuffet, Jean Fautrier, Rafael Canogar, Roger Bissière, Hans Hartung, Alfred Manessier and Zao Wou-Ki. Kinetic art and geometric abstract art are exemplified in the works of Victor Vasarely, Nicolas Schöffer, Josef Albers, Alberto Magnelli and Serge Poliakoff. New Realism is exhibited in the works of Claudio Bravo, Arman, Jean-Olivier Hucleux, George Segal, Edward Kienholz, Christo and Jean Ipousteguy.
