Excerpts from (relatively) recent Richard Polsky Artnet articles mentioning Marlene Dumas -
"entering the realm of the absurd are two Marlene Dumas paintings, each estimated at $800,000-$1.2 million"
"Marlene Dumas -- This year's auction darling. Her outrageous prices for awkwardly painted (to the point of looking unfinished) figures continues to amaze veteran auction watchers. At over a million dollars for a "good" painting, surely collectors have options. Outlook for 2005: Status quo"
"whoever decides to bid on lot 55, the Marlene Dumas painting, in Sotheby’s evening sale on Nov. 9 should think long and hard. With an estimate of $600,000-$800,000, The Taboo (2000) represents a highly risky purchase. Not only is the canvas sloppily painted, which is unfortunately typical of the artist, but it raises an even greater question -- who is Marlene Dumas and why do her pictures routinely carry (and bring) six-figure prices?"
In this article Polsky calls David Hockney "one of our ten finest living painters". I'm really curious as to who he thinks the other nine are but he won't tell - my guess is that he would include Robert Ryman, Jules Olitski, Wayne Thiebaud, and Jasper Johns on his list.
