Auction introduction: This May, Christie’s presents 16 masterpieces from the collection of S.I. Newhouse, as the third in a series of historic sales from the legendary Condé Nast co-owner who built one of the greatest art collections of the 20th century. As the long-time chairman of the media empire that included The New Yorker, Vogue, Vanity Fair and Architectural Digest, Mr. Newhouse was a hugely influential figure in American cultural life and his collection of modern and contemporary masterworks remains ‘one of the most sought-after groupings of art in private hands.’ Highlights from the spring selection include a rare, early 1947 enamel painting by Willem de Kooning (Orestes), an intricate Picasso portrait of Lee Miller (L'Arlésienne) and a Twombly Bolsena painting among many others.
