Victor Vasarely. Tupa-3, 1972. Victor Vasarely, widely regarded as the father of Op Art, was one of the most influential figures of 20th-century abstract art. His research into visual perception, color, and geometry transformed the relationship between viewer and image, creating compositions capable of producing movement, depth, and vibration through precise mathematical structures. 'Copyright 1975 Editions du Griffon, Neuchâtel/Suisse' on the back. Dry stamp of the Vasarely Foundation. Photolithography on gloss paper. Total dimensions: 27 x 27 cm. Fine condition. In Tupa-3 (1972), Vasarely develops one of his most characteristic optical architectures, built from repeated elliptical modules that gradually deform to create the illusion of a three-dimensional volume floating in space. The combination of blue, orange, and yellow tones produces a dynamic effect in which the form seems to expand and contract simultaneously, transforming the flat surface into an almost sculptural structure. The work belongs to the artist’s mature period, when his visual language reached a perfect synthesis between art and science. For Vasarely, painting had to be universal, based on reproducible systems capable of transcending individual gesture, anticipating ideas that today are associated with digital art and generative design.
