LONDON David Bowie's private art collection, including works by Henry Moore and Damien Hirst, will go on display to the public for the first time before heading for auction later this year, Sotheby's said on Thursday. The "Bowie/Collector" three-part sale in November will feature around 400 items from the pop icon's private collection and is seen fetching "in excess of 10 million pounds" ($13.24 million), a spokeswoman for the auction house said.
