Art collection worth $150M heads to auction

DALLAS — An art collection worth an estimated $150 million that belonged to the late Texas oil and ranching heiress Anne Marion is going up for auction this spring in New York.

Sotheby’s said Wednesday that Marion’s private collection includes works by Andy Warhol, Roy Lichtenstein and Franz Kline.

Marion, who founded the Georgia O’Keeffe Museum in Santa Fe, N.M., died last year at age 81. Marion and her husband, John, a former Sotheby’s chairman and auctioneer, established the museum in 1997.

Marion was the heiress to the historic Four Sixes Ranch in King County in West Texas.
