Lawsuits claim Knoedler made huge profits on fakes

For more than a dozen years the Upper East Side gallery Knoedler & Company was “substantially dependent” on profits it made from selling a mysterious collection of artwork that is at the center of a federal forgery investigation, former clients of this former gallery have charged in court papers. The analysis is based on financial records turned over as part of a lawsuit against the gallery filed by Domenico and Eleanore De Sole, who in 2004 paid $8.3 million for a painting attributed to Mark Rothko that they now say is a worthless fake. The Rothko is one of approximately 40 works that Knoedler, which closed last year, obtained from Glafira Rosales, a littleknown dealer whose collection of works attributed to Modernist masters has no documented provenance and is the subject of an F.B.I. investigation. Between 1996 and 2008, the suit asserts, Knoedler earned approximately $60 million from works that Ms. Rosales provided on consignment or sold outright to the gallery and cleared $40 million in profits. In one year, 2002, for example, the complaint says the gallery’s entire profit — $5.6 million — was derived from the sale of Ms. Rosales’s works. “Knoedler’s viability as a business was substantially — and, in some years, almost entirely — dependent on sales from the Rosales Collection,” the De Soles claimed last month in an amended version of the suit they filed this year. While the forgery allegations are well known and have been the subject of three federal lawsuits against Knoedler, the recent filings expand the known number of Rosales artworks that were handled by the gallery, which was in business for 165 years, and assert that they played a pivotal role in the gallery’s success. After the F.B.I. issued subpoenas to the gallery in the fall of 2009, Michael Hammer, Knoedler’s owner, halted the sale of any Rosales works. Knoedler ended up losing money that year and in 2010, the court papers say. http://www.nytimes.com/2012/10/22/arts/design/knoe...
