‘Halo effect’ of powerful art dealers’ collections boosts Sotheby’s sale
Sotheby's held a successful three-part evening auction in New York on May 15, 2025, achieving a total of $154.2 million in hammer sales ($186.1 million with fees), within its pre-sale estimate. The sale included 12 lots from the estate of late dealer Barbara Gladstone, which sold 100% for $15.1 million, and 15 works from the collection of Daniella Luxembourg, which brought $33.6 million. The main event, Sotheby's The Now and Contemporary evening auction, featured 41 lots—including works from the Dorothy and Roy Lichtenstein collection and three deaccessioned by US museums—and achieved a 93% sell-through rate, hammering $105.4 million. A standout was Andy Warhol's 'Flowers' (1964) from the Gladstone estate, which sold for $3.1 million hammer, more than double its high estimate.
