Claes Oldenburg and Coosje van Bruggen have been working in partnership since 1976. Together they have executed over 40 large-scale, site-specific projects that establish direct contact with a wide audience into various urban settings in Europe, Asia, and the United States. Their collaboration has extended to smaller-scale park and garden sculptures as well as to indoor installations. Published in association with the Castello di Rivoli, this major retrospective catalog focuses on the close relationship between the concepts of sculpture and architecture in the work of the artists and is the first to trace the development of their artistic itinerary from the mid-1980s up to the present. Lavishly illustrated the catalog features the works in chronological order, elucidated by text introducing each of the body of works. In the section devoted to large-scale projects, 22 works are examined and illustrated with drawings, models, and photographs. This long-awaited monograph includes an interview with the artists, an anthology of texts, a bio-bibliography, and two never-before-seen works: Popagesy, produced especially for the exhibition, and Three Way Plug, which addresses the artists' own history.
