Fifteen sales records were broken at a Sotheby’s auction in New York this week as the art market continues to explode. Francis Bacon’s Lying Figure with Hypodermic Syringe sold for $15 million, the most ever paid for a Bacon work, while sculptor Anish Kapoor’s “untitled carved alabaster sculpture from 1999 generated $2.3m, about five times the sum it had been predicted to earn.”
