Auction house Christie's Asia chairman Anthony Lin displays a rare Tang-style celadon-glazed amphora which set a world record for a monochrome porcelain in Hong Kong November 1, 2004. The porcelain from the Qing dynasty Yongzheng period (1723-1735) fetched HK$17,432,750 (US$2,233,814), more than three times the pre-sale estimate. REUTERS/Bobby Yip BY
