The 1900s ended only 13 years ago, but works of 20th-century design are increasingly being sought by collectors, with some works bringing six- and even seven-figure sums as was seen at last month’s 20th Century Design auctions in New York.

The two top sellers at Christie’s sale of the Steven A. Greenberg Art Deco collection each brought over $1 million, while the 10 top sellers at its decorative art and design auction sold for six-figure sums with all but one selling above their high estimates.
