Claes Oldenburg was a Swedish-American artist born in 1929 who was influential in the Pop Art movement of the 1960s. He is known for his large-scale sculptures that depict everyday objects in exaggerated sizes and unusual materials. One of his most famous works is Knife Ship I, a 31-foot tall sculpture of a knife embedded in a ship made of vinyl-covered wood, steel and aluminum. Oldenburg also created sculptures of food, like his 1962 work Glass Case with Pies, which depicted assorted pies enclosed in a glass case.
