NEW YORK, NY.- Christie’s International announced the third annual Green Auction: BID to Save the Earth, to be hosted by Christie’s at Rockefeller Center on April 11, 2012, just two weeks before Earth Day. A world-class companion auction powered by charitybuzz will run online from March 29 to April 19. The Green Auction is a borderless collaboration of individuals, organizations, and businesses who are engaged, in spirit and action, in the protection and conservation of the environment.
