Wall Street isn’t normally the place to go to talk about fine art, but Sotheby’s big spring art sale in New York has financial players buzzing about blockbuster paintings being bought and sold by some of their own.

This year’s sale kicks off Wednesday evening with an auction of the collection of the late Wall Street financier Ted Forstmann. Among the 50 works that belonged to the Forstmann, Little & Co. founder, who died in November, are paintings by Roy Lichtenstein, Paul Gauguin, Jean-Michel Basquiat and Pablo Picasso. The collection could raise as much as $75 million, led by Picasso’s 1941 portrait of his lover and fellow artist Dora Maar, valued at $20 million to $30 million.

But the night’s show-stopper will be a 1895 pastel, “The Scream” by Edvard Munch, which some experts are expecting to fetch as much as $200 million.

The seller, Petter Olsen, is a Norwegian industrialist whose father, Thomas, was a patron of Munch’s. He has owned the painting for the past 70 years.
