Promo1_Warhol-200-One-DollaSotheby’s post-war and contemporary art auction saw more then $130 million in sales last night. Helping nearly double the auction’s pre-sale estimate was Andy Warhol’s cash tribute. The pop master’s 1962 painting “200 One Dollar Bills,” sold for $43.7 million, triple its estimated price. That means every single dollar in the 7.5-foot screenprinted painting is worth more than $218k. |Artinfo|
