The same year, he moved to Paris and worked as an advertising graphic designer. Ten years later, he plunged into the paths of abstraction that would lead him to optico-kinetic art. He defined this art of time and space in 1955 in the Manifeste Jaune, co-written with Ponthus Hulten and Roger Bordier for the exhibition "Le Mouvement" at the Galerie Denise René. This event was the real starting point of the Op'Art adventure and presented him alongside Yacoov Agam, Pol Bury, Alexander Calder, Jesùs-Rafael Soto and Jean Tinguely. In the manifesto, Vasaraly lays the foundations of the plastic unity from which optical illusion proceeds. Finally, he proclaims a new era of the Multiple: "the idea of the plastic work resided until now in an artistic approach, and in the myth of the single piece; today it is found in the conception of a possibility of recreation, multiplication and expansion".
