This book is the first catalogue of Yona Friedman as an artist. In fact, it presents for the first time the whole work of art of this pivotal figure, well-known as an architect and theorist since the 60s of the last century. The catalogue shows an extensive collection of visual materials, including images, cartoons and pictograms, drawn by Yona Friedman in order to replace the text with the image in his way of thinking. “Drawing for my own pleasure meant that I enjoyed looking at my drawings, and so I pasted them on the walls of my home, of my studio, on furniture, and on the refrigerator. Indeed, I produced them as the personal landscape of my surroundings, even decorating the ceiling of my atelier at blvd Pasteur and my home at blvd Garibaldi.” Text: Maurizio Bortolotti, Jean-Baptiste Decavèle, Yona Friedman, Hou Hanru, Hans Ulrich Obrist
