Last October, Clapton sold one of his Gerhard Richter paintings at auction for $34.2 million, which at the time, set an auction record for the German abstract artist, who is still alive. Now Clapton is unloading another Richter painting. It is titled Abstraktes Bild and it’s estimated to sell for $20- to $25-million when Christie’s auction house in New York puts it on the block on November 12th.
