The Hague painter Will Leewens, together with Willy and Frans Boers, Roëde, Hussem, Ouborg and Nanninga, was a member of the experimental artists' group 'Vrij Beelden' (1947-1953) in the 1940s. Like the members of the Cobra group, they are opposed to traditional, figurative art. In the sixties the painter joined the Informelen, who continued the abstraction and experimented with new materials.
