Andy Warhol, Jeff Koons, John Chamberlain: Art Auctions Highlights, May 9-13 (PHOTOS)

It's been a week of triumph and disappointment at the auction houses, with Jeff Koons and Abstract Expressionists snubbed in favor of more, more, always more Andy Warhol. Some artists made off like bandits, including John Chamberlain, whose 1958 assemblage more than doubled estimates at Sotheby's and became his highest-selling piece ever. But some works had to be bought in, like Ed Ruscha's 1984 painting, "HONEY...I TWISTED THROUGH MORE DAMNED TRAFFIC TO GET HERE" which didn't live up to expectations at separate Sotheby's auction. The New York Times opined, "Substance or style were clearly irrelevant this week. Size and name recognition were enough." See how your opinions stack up with more highs and lows of this week's auctions in the slideshow below.
