Information:

Richard P. Hartmann had invited Hundertwasser, Ernst Fuchs and Arnulf Rainer to his gallery in Munich to perform an action in the spirit of the "Pintorarium". While Fuchs and Rainer prepared themselves for a body painting and the models were ready, Hundertwasser took the opportunity to strip off his clothes and read his speech in the nude, in which he condemned the enslavement of mankind to the sterile grid system of architecture. Fuchs and Rainer subsequently went ahead with the body painting, whereas Hundertwasser had refused to do it in front of the audience from the beginning. He made up for it on the next day without audience.
