Two works by the late gay artist Andy Warhol brought the top prices at a Christies sale of postwar (19451970) art on Wednesday, reports The New York Times. A 1964 silkscreen from Warhols Large Flowers series went for the most, at $8.4 million. It measures 82 by 164 inches and depicts two flowers, one pink and one red. It was one of only four executed on so large a scale and the last to still be in private hands. The next highest price was paid for the 1962 piece Orange Marilyn. Warhol works were also put on the block at Sothebys, where the 1962 work Group of Five Campbells Soup Cans went for $3.7 million on Tuesday.
