Time Out says
Born in Delft, The Netherlands, Schoonhoven (1914–1994) was cofounder of Nul, begun in 1960 as the Dutch equivalent of Germany's ZERO group. His aesthetic was similarly reductive, confined to monochromatic, geometrically abstract compositions covered with rhythmically repeating recessed spaces. These formed honeycombed patterns and the like, making his works seem more like wall reliefs than paintings. Still, while his approach shared affinities with Minimalism, his pieces were largely crafted by hand out of cardboard and paper. This show collects examples dating from the 1950s to the mid-’70s.
