Victor Vasarely Structure Universelle du Damier, 1971 Set of 8 offset lithograph prints published by Editions du Griffon in 1975. Heavy weight paper with a glossy finish. Each print is certified by the publisher on the reverse. Size : 27 x 27 cm each. Enclosed in a silver cardboard portfolio Victor Vasarely’s complex paintings and sculptures helped define the ethos of the Op art movement. The artist’s vibrant compositions feature a mix of rigidly geometric and more fluid forms which, when combined with monochromatic or diverse color palettes, produce the optical illusions that give Op art its name.
