Cubi XIII is part of David Smith's final and most famed series of sculptures. Smith polished the stainless steel so that it would reflect the changing colors of its surroundings, especially when placed outdoors, among trees. Although the burnished surface is constructed of basic geometric shapes, it also reveals a painter's sensibility.
