of his large abstract paintings. By 2004, Richter's annual turnover was $120 million. At the same time, his works often appear at auction. According to artnet, an online firm that tracks the art market, $76.9 million worth of Richter's work was sold at auction in 2010. Richter's high turnover volume reflects his prolificacy as well as his popularity. As of 2012, no fewer than 545 distinct Richter's works had sold at auctions for more than $100,000. 15 of them had sold for more than $10,000,000 between 2007 and 2012. Richter's paintings have been flowing steadily out of Germany since the mid-1990s even as certain important German collectors – Frieder Burda, Josef Fröhlich, Georg Böckmann, and Ulrich Ströher – have held on to theirs. Richter's candle paintings were the first to command high auction prices. Three months after his MoMA exhibition opened in 2001, Sotheby's sold his Three Candles (1982) for $5.3 million. In February 2008, the artist's eldest daughter, Betty, sold her Kerze (1983) for £7,972,500 ($15 million), triple the high estimate, at Sotheby's in London. His 1982 Kerze (Candle) sold for £10.5 million ($16.5 million) at Christie's London in October 2011. In February 2008, Christie's London set a first record for Richter's "capitalist realism" pictures from the 1960s by selling the painting Zwei Liebespaare (1966) for £7,300,500 ($14.3 million) to Stephan Schmidheiny. In 2010, the Weserburg modern art museum in Bremen, Germany, decided to sell Richter's 1966 painting Matrosen (Sailors) in a November auction held by Sotheby's, where John D. Arnold bought it for $13 million. Vierwaldstätter See, the largest of a distinct series of four views of Lake Lucerne painted by Richter in 1969, sold for £15.8 million ($24 million) at Christie's London in 2015. Another coveted group of works is the Abstrakte Bilder series, particularly those made after 1988, which are finished with a large squeegee rather than a brush or roller. At Pierre Bergé & Associés in July 2009, Richter's 1979 oil painting Abstraktes Bild exceeded its estimate, selling for €95,000 ($136,000). Richter's Abstraktes Bild, of 1990 was made the top price of 7.2 million pounds, or about $11.6 million, at a Sotheby's sale in February 2011 to a bidder who was said by dealers to be an agent for the New York dealer Larry Gagosian. In November 2011, Sotheby's sold a group of colorful abstract canvases by Richter, including Abstraktes Bild 849-3, which made a
