Billionaire collector Steven Cohen, who recently added Giacometti's "Chariot" (1950) to his vast art collection for a cool $101 million, donated a tour of his Greenwich, Connecticut collection to the Foundation for Prader-Willi Research charity auction last week, as per "Page Six." Cohen, who was also actively involved with the Robin Hood Foundation for many years, was revealed as the buyer of the Giacometti sculpture, which sold on a single $90 million bid at Sotheby's on November 4 (see "$101 Million Giacometti Leads Sotheby's $400 Million Imp Mod Evening Sale") to David Norman, Sotheby's co-chairman of Impressionist and modern art worldwide, who was bidding for his client.

No word yet on whether the tour was successfully sold at the charity auction, or for how much—the Foundation for Prader-Willi Research did not respond for comment.
