«I LIKE MONEY ON THE WALL»

Feb. 12 (Bloomberg) -- An Andy Warhol dollar-sign silkscreen and an Yves Klein painting of a naked model were snapped up by diamond dealer Laurence Graff last night as buyers splashed out another 39.1 million pounds ($61.4 million) on contemporary art.Sellers of the two works at Christie’s International in London made handsome profits, dealers said, as Graff’s spend in the February auctions totaled at least 15 million pounds. Last week, he paid 8.1 million pounds for a Pablo Picasso portrait.
