A Real Bargain: An antiques dealer bought two stolen masterpieces worth almost $3 million for $210 at a street market, Sotheby’s auction house said Friday. The company said the man learned the true value of the 18th-Century portraits by Thomas Gainsborough and Sir Joshua Reynolds when he brought them to Sotheby’s in a black plastic garbage bag for valuation. Sotheby’s art expert Lucy Hodson told reporters she recognized the works, stolen from London law offices in a 1990 robbery in which a guard was beaten unconscious.
