June 5: first experiments with the "living brushes" technique in Robert Godet’s apartment on Ile Saint-Louis in Paris. A great friend of Yves Klein, with whom he shared a genuine intellectual complicity, Robert Godet was a disciple of Gürdjieff, a judo instructor and occult philosopher. In the course of the evening, Yves covered in blue paint the naked body of a young woman, who, through a series of rotating movements, left her bodily prints on a sheet of paper set on the floor, until the support was fully saturated. The result was a blue monochrome.

For the Gelsenkirchen Opera House — designed and decorated by an international team of artists and architects — Klein created six monumental pieces of foremost importance in his work: four blue, ten-meter-high relief-sponges (two for the long wall of the main hall, two for the coat-check on the lower level) and two seven-meter-long by twenty-meter blue monochromes, intended for the lateral walls of the main hall. The works were wire-reinforced plaster reliefs, covered over with natural sponges and spray-painted in IKB blue.
