the Grossmünster cathedral in Zurich between 2006 and 2009. Exhibitions Polke had his first one-person show at Galerie René Block, West Berlin, in 1966, and in 1970 he had his first solo exhibition at Galerie Michael Werner. His first solo exhibition in New York, of paintings made at least a decade earlier, was at the Holly Solomon Gallery in SoHo in 1982. Following a 1987 show at the Milwaukee Art Museum grouping Warhol, Beuys and Polke, the Museum of Contemporary Art, Chicago mounted a solo show for Polke in 1991. Polke exhibited at three documenta and several Venice Biennial exhibitions. By the latter years of his life, Polke's artistic achievements were being recognised in large-scale exhibitions around the world, with solo shows at Tate Modern in 2003–2004, Tokyo's Ueno Royal Museum in 2005 and the Getty Center in Los Angeles in 2007. In 2007, the "Museum Moderner Kunst" (MUMOK) held an exhibition of Polke's work entitled "Sigmar Polke: Retrospektive". Also in 2007, Axial Age (2005–2007), a monumental cycle of paintings, was shown for the first time at the 2007 Venice Biennale, with the wish explicitly expressed by the artist that the work should remain on display in Venice. Polke is scheduled to have a retrospective "Alibis: Sigmar Polke 1963–2010" shown at The Museum of Modern Art in New York, from 19 April to 3 August 2014, then travels to Tate Modern, London, United Kingdom and Museum Ludwig, Cologne, Germany.

The artist John Baldessari described Polke as an "artist’s artist". Today, Polke is often grouped with Gerhard Richter because both came of age and experimented in West Germany in the 1960s. Art market Polke achieved early success for his paintings and drawings of consumer goods. His mid-1960s works remain the artist's most recognizable and have performed the best at auction. A first record price for Polke's work at auction was established at Christie's in London in 2007 when 2.7 million pounds (then $5.3 million) were paid for a 1966 canvas titled Strand (Beach). At a Sotheby's auction in London in 2011, Polke's City Painting II (1968) sold for $7.4 million, and his Jungle (1967) established a new
