Treasures priced at $100 million by 20th-century masters Jackson Pollock and Constantin Brancusi will lead Christie’s New York’s marquee May art sales, coming from the collection of media magnate S. I. Newhouse, Artnet News has revealed.

While Christie’s has yet to confirm Artnet’s report, those two estimates, if met, would far exceed those artists’ current auction highs. Numbering as many as 40 works, the collection encompasses examples by giants like Jasper Johns and Pablo Picasso, and is reportedly valued at $450 million.
