Based on observations of primates in a zoo and accompanied by an expert's text, these drawings by Claudia and Julia Müller document animals' behavior. Through the notions of play, manipulation of objects, and "performance," this artists' book, designed by Christoph Keller, intertwines drawings, texts, and photographs in an allegorical reading of monkeys' activities as a somewhat art-related form. * * Published with the Kunstverein Friedrichshafen beim Zeppelin Museum. * * The publication is part of the series of artists' projects edited by Christoph Keller. *
