Jerry Hall's art collection sells for $4 million

An auction of art owned by model Jerry Hall has racked up nearly 2.5 million pounds ($4 million) in sales.

Sotheby's said Saturday that the highest price in the two-day sale was for a painting, "Head of Helen Gillespie," by the artist Frank Auerbach. It sold for nearly 1.1 million pounds ($1.76 million), above the estimate of 900,000 pounds ($1.4 million).

Hall acquired the painting in 1997.

Strong bidding pushed up the price of a nude study of Hall by Lucien Freud, painted when she was eight months pregnant with her fourth child with former husband Mick Jagger. It sold for 601,250 pounds ($961,579), double the lower end of the pre-sale estimate.

The two-day Contemporary Art Sale included 14 works owned by Hall. Four failed to sell.
