May: Yves Klein published Yves Peintures and Haguenault Peintures. These two collections of monochromes were put together and published in Fernando Franco de Sarabia’s engraving studios in Jaen, in the Madrid area. Pascal Claude’s preface was made up of black lines instead of text. The ten color plates consisted of single-colored rectangles, cut out in paper and accompanied by an indication of their size in millimeters. Each plate indicated a different place of creation: Madrid, Nice, Tokyo, Paris. In Haguenault Peintures, mention was also made of collections.
