Original drawing in ballpoint pen in blue on wove paper, accomplished and signed by John Cage, Allan Kaprow, Al Hansen, and Wolf Vostell as well as dated 1986 by Al Hansen. The outline of the face, eyes and nose appear to be accomplished by Cage, whose signed name "John Cage" constitutes the nostrils, beneath which Allan Kaprow's name composes a mustache over a mouth, while the figure's hair is clearly accomplished by Hansen, whose name and title outline the head "Al Hansen Kunstlaboratorium Köln." In a lighter, rather faded ink, "Vostell" forms the right eye. Previously exhibited in “The Art of Collecting” at the Museum Kunst Palast Düsseldorf Foundation, 2007. In fine condition.  7.8 x 10.5 inches (26 x 19.5 cm).  

In 1957 Al Hansen enrolled in John Cage's composition class at The New School. He had no prior knowledge of music, but this class became a catalyst for a community of artists performing and sharing ideas and provided the foundation for his later Fluxus event scores. The American performance artist, installation artist, painter, and assemblagist Allan Kaprow helped to develop the "Environment" and "Happening" in the late 1950s and 1960s, as well as their theory. German painter and sculptor Wolf Vostell is considered one of the early adopters of video art and installation art and pioneer of Happenings and Fluxus.
