New York Times: Hong Kong’s anti-pollution organization, the Clean Air Network, has launched a new effort to raise awareness and fight for clean air: an art auction. Fifty-one environment-inspired works of modern art went on display Monday in Hong Kong’s financial district. Sotheby’s will auction them off on 4 April, part of the auction house’s twice-yearly sale of contemporary Asian art. Many of the artists, who include well-known names from Hong Kong and elsewhere, created works especially for the event. The Clean Air Network has tried imaginative approaches to campaigning before, including a spoof infomercial featuring Hong Kong actor Daniel Wu selling canisters of “fresh air,” which became an instant hit among YouTube users. In her New York Times‘s article, Bettina Wassener describes some of the pieces to be auctioned.
