The Hague painter Will Leewens, brother-in-law of Jan Roëde, exhibited together with Willy and Frans Boers, Roëde, Hussem, Ouborg and Nanninga in the post-war years with the experimental artist group 'Vrij Beelden' (1947-1953). Like the members of the CoBrA group, they oppose traditional, figurative art. In the late 1950s, Leewens briefly joined the Informelen. He experiments with new use of materials but remains faithful to his own design language - rectangles and squares. In the years that followed, round shapes and colours dominated in his work, which he arranged side by side.
