Offered here is a beautiful screen print from 1990 by Mark Verstockt, signed and numbered. Marc Verstockt took classes at the Royal Academy of Fine Arts of Antwerp, together with Dan Van Severen. They became followers of constructivism. He immersed himself in abstraction and the study of geometric shapes. He said: Geometry is secondary to me, it is the structure that counts. Verstockt produced sculptures, the most famous being the monumental sculpture 'Signaal' in Sint-Niklaas. He experimented with video and printing. In 1971 he published 'This is not a book', a pop-up book with geometric shapes and a life-size poster. Verstockt was active as a graphic designer for book publications, including for the Liège Editions du Perron. As a theorist, Verstockt made his name in 1982 with 'The Genesis of Form, from Chaos to Geometry', an in-depth study of the three primordial forms: the circle, the square and the triangle.
