Jackson Pollock’s paintings are no strangers to high prices at auction, and his Number 5 is no different. In November of 2006, Number 5, painted in Pollock’s unique drip technique, was sold for $140 million dollars, the highest price ever paid at auction for a painting, to an unknown buyer. This price exceeded both the high price paid for his Blue Poles, which sold in 1973, as well as Gustav Klimt’s Portrait of Adele Bloch-Bauer I, which previously held the high price record. Using his entire body to paint in a method called “action painting,” Pollock dripped and splattered layer upon layer of paint to create his chaotic patterns.
