Vibrant colour was essential to the paintings of the American pop artist Roy Lichtenstein (1923-1997), and when he began exploring outdoor sculpture in the late 1970s, vivid hues-often achieved through the use of recently developed industrial paints and coatings-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 his studio materials, interviews with his assistants, and a thorough technical analysis of the sculpture Three Brushstrokes, now in the collection of the J. Paul Getty Museum. The book concludes with a chapter showing various options for the care, conservation, and restoration of Lichtenstein's sculptural works, making this an essential resource for conservators, curators, and others interested both in the iconic artist and modern sculpture in general.
