American postminimalist artist Richard Tuttle (born 1941) has worked in close collaboration with the Kunsthaus Zug in Switzerland as its informal "in-house artist" for almost 20 years now. Through fragile, mostly small, subtle paintings as well as sculptural objects and three-dimensional installations, Tuttle continues to explore special features of the museum´s architecture and selected works from its collection, exploring larger questions of endurance and continuity, rhythm and repetition across cultures globally. Use of Time is a slim, elaborately designed artist´s book--published in a limited edition of 850 copies--with 18 cards loosely bound by square knots and round grommets. The book´s circular design reflects Tuttle´s affinity for the Asian concept of time as a cycle and eternal return of the same, while also demonstrating the currency and reliability of traditional bookbinding through the radical renewal of art.
