The art of Anselm Kiefer (b. 1945, Donaueschingen, Germany) is a mainstay of the Guggenheim Museum Bilbao Collection, which includes more than eleven large-format works produced in the 1980s and 1990s. Most of these works were acquired specifically to be displayed in the Museum. Among them are books, paintings, sculptures, and woodcuts. Many of these richly textured pieces sometimes incorporate organic materials like sunflower seeds or asparagus.
