Victor VASARELY (1906-1997). Autograph manuscript; 5 pages and a quarter in-4 (some edges slightly faded). Very interesting reflections on art, the integration of his artistic work into urban space, the role of colors, and the "polychrome city". They are numbered from 1 to 22. "The world is still attached to the idea of the unique work of art reserved for the privileged elite. [...] Today's leitmotiv is 'art must take to the streets': a statement that is both accurate and equivocal. Advertising, propaganda, signs of all kinds, certain manifestations of pop-art, fashionable environments, are well and truly in the streets and public squares, creating an anarchic atmosphere of festivity and excitement. It's not just a question of enjoying fashion, but of creating a style, the STYLE of OUR TIME [...]. Humanity deprived of its intrinsic plasticity inexorably becomes a sick humanity. [...] In addition to the poetic beauty of the living cell, the artist must project his imagination into urban spaces and create works on a city scale. A veritable "planetary folklore" was thus born, to the delight of all. [...] We know that reds and oranges speed up the heartbeat, blues are calming (Saturnian), mauves are melancholy, yellows are joyful, greens plunge us into a kind of pantheism... We know a lot about the balancing action of harmonic colors and the exciting action of contrasting colors [...]. There is growing interest in the polychrome city. I'm being approached from all sides to propose solutions, to collaborate with teams of architects and urban planners. At the Rond Point des Champs Elysées, the Porte de Maillot, the Quai d'Orsay, La Défense, in these new complexes to be built, I also have my say, as well as in Créteil le "Neuf", which aims to be the most modern city in France. [...] I repeat: I don't think of myself as an architect, but I have sought out and found the plastic alphabet of form and color. I have perfected a method that is likely to develop into an incomparable style. My first plastic units date back to my early youth: the "Fille-Fleur", the "Arlequin" and the "Martiens" bear witness to this. Since then, I've never stopped working on the idea. My countless "prototype departures", my "grand compositions", my "deep kinetic works in transparency", my "mirror-image" sculptures and reliefs are all milestones of architectural integration. The polychrome city of the future is there in my studio, it will be in Gordes, exhibited didactically, and it's a question of transposing these discoveries into urban volumes and spaces, into the immense perspective of highways and into aerial vision". A black-and-white photograph of Vasarely with Frédéric de Towarnicki (23.5 x 17 cm) is included.
