The first book-length study to examine the materials and techniques used in the fabrication and painting of the American pop artist Roy Lichtenstein's outdoor sculpture. Vibrant color was essential to the paintings of the American pop artist Roy Lichtenstein (1923–1997), and when he began exploring the creation of outdoor sculpture in the late 1970s, vivid hues remained an important part of his artistic vocabulary. Today, preserving these remarkable works after they have endured decades in outdoor environments around the world is an issue of pressing concern. This abundantly illustrated volume is based on extensive archival research of Lichtenstein's studio materials, interviews with his assistants, and a thorough technical analysis of the sculpture Three Brushstrokes. The book concludes with a chapter showing various options for the care, conservation, and restoration of his sculptural works, making this an essential resource for conservators, curators, and others interested both in the iconic artist and modern sculpture in general.
