A Joan Mitchell diptych and a rare stack by Donald Judd: our pick of the May auctions

The Art Newspaper highlights five major lots from New York's May 2025 auctions. Phillips offers Joan Mitchell's diptych 'Plain' (1989), estimated at $5-7 million, from the collection of late Miami art patron Tina Hills. Christie's presents Donald Judd's rare copper and red Plexiglas 'Untitled (Stack)' (1969), estimated at $10-15 million, from the Minimalist collection of the late Henry S. McNeil Jr. Sotheby's leads with Jean-Michel Basquiat's 'Museum Security (Broadway Meltdown)' (1983), estimated above $45 million, and Mark Rothko's 'Brown and Blacks in Reds' (1957), estimated at $70-100 million from the collection of late dealer Robert Mnuchin.

Richter works from gallerist Marian Goodman and Donald Judd pieces lead Christie's New York auctions

I lavori di Richter della gallerista Marian Goodman e le opere Donald Judd guidano le aste di Christie’s a New York

Christie's New York spring sales opened on May 20, 2026, with two major collections: the minimalist art collection of Henry S. McNeil Jr. and works by Gerhard Richter from the collection of legendary gallerist Marian Goodman. The 42-lot session achieved $162.7 million, with 98% sold by lot. The 21st Century Evening Sale alone reached $136.8 million, a 42% increase over May 2025 and Christie's highest result for the category in five years. Top lots included Donald Judd's "Untitled" (1969) at $12.8 million—a new auction record for a Judd stack—and Richard Artschwager's "Two-Part Invention" (1967) which soared to $635,000 from an estimate of $60,000–80,000. The Goodman collection of eight Richter works, all guaranteed, generated $78.8 million, exceeding expectations.

‘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.

Record-breaking female Surrealists spice up underwhelming Christie’s New York sales

Christie’s New York spring sales brought in a combined $489 million across two evening auctions, including the Leonard and Louise Riggio collection ($272 million) and a 20th-century evening sale ($216 million). While sell-through rates were high at 94%, bidding was shallow and several high-profile lots underperformed: a Mondrian estimated at $50 million sold for $47.6 million, a Magritte from the Empire of Light series matched its 2023 price at $34.9 million, and a Lucio Fontana canvas that sold for $14 million in 2017 fetched just $7.5 million. Andy Warhol’s Big Electric Chair was withdrawn last minute amid a reported $10 million gap between seller and buyer expectations. The sales were bolstered by third-party guarantees and came hours after news of a temporary US-China tariff détente.
