Modern and Contemporary Outdoor Sculpture Conservation: Challenges and Advances

Artist Naum Gabo with Head No. 2, enlarged version (1966), Tate, London. When Head No. 2, made of Cor-Ten steel, was displayed outdoors, water collecting in pockets hastened corrosion. Gabo made another version in stainless steel for outside display, and the Cor-Ten sculpture was brought indoors. Photo: Sir Norman Reid, courtesy Nina Williams.
