Sotheby’s Secures Monumental Rothko from Legendary Collector Robert Mnuchin, Anchoring $130 Million+ May Sale
New York, March 11, 2026 — In a move poised to electrify the spring auction season, Sotheby’s has announced the consignment of a carefully curated selection from the personal collection of the late Robert E. Mnuchin, one of the art world’s most discerning dealers and collectors. The group of 24 masterworks, estimated to achieve in excess of $130 million, will headline the house’s May auctions in New York, led by Mark Rothko’s towering 1957 masterpiece Brown and Blacks in Reds, carrying a pre-sale estimate of $70–100 million.
Mnuchin, who passed away in December 2025 at age 92, built an extraordinary legacy bridging finance and fine art. As founder of Mnuchin Gallery and a former Goldman Sachs partner, he cultivated an eye for postwar abstraction that few could match. His collection, assembled alongside his wife Adriana over decades, focused on museum-caliber examples of modern and contemporary art—works chosen not for fashion but for their profound ambition and emotional resonance.
At the forefront stands Rothko’s Brown and Blacks in Reds, a nearly eight-foot canvas of luminous, contemplative fields in deep crimson, black, and brown tones. Painted in 1957—a pivotal year for the artist—this work echoes the palette and spiritual intensity of Rothko’s famed Seagram Murals commission, which followed shortly after. Originally acquired by Joseph E. Seagram & Sons around the time of its creation, it has graced major exhibitions, from the Guggenheim’s 1978–79 traveling retrospective to Tate London’s 1987 survey and the recent Fondation Louis Vuitton show in Paris. One of only 15 monumental canvases (over 90 inches) Rothko produced that year, most of which now reside in institutions like the National Gallery of Art in Washington, D.C., and the Museum of Contemporary Art in Los Angeles, this painting has remained in Mnuchin’s hands for more than two decades.
Sotheby’s will present 11 highlights from the collection in a dedicated evening auction, with additional pieces integrated into its Modern and Contemporary day sales. The lineup also includes another Rothko from 1949 (estimated $15–20 million) alongside works by titans such as Willem de Kooning, Franz Kline, Jeff Koons, and David Hammons—reflecting Mnuchin’s lifelong passion for bold, transformative abstraction.
“This is a collector at heart,” said Lisa Dennison, Chairman of Sotheby’s Americas, in a statement accompanying the announcement. Mnuchin’s selections reveal an uncompromising pursuit of quality and depth, qualities that have defined his influence across the market for generations.
The consignment arrives at a moment of renewed optimism in the art world. Following a strong rebound in U.S. auction sales last year and Sotheby’s blockbuster November totals, the house is positioning this sale—and others like Christie’s concurrent offering from the S.I. Newhouse estate—as catalysts for continued momentum. A special public exhibition of select works opens at Mnuchin Gallery from March 11–15, with highlights traveling to Hong Kong, Los Angeles, London, and back to New York for pre-sale viewings at the Breuer building.
For collectors, advisors, and institutions alike, the Mnuchin trove represents more than blue-chip assets: it is a rare opportunity to acquire pieces from one of the most respected private holdings of the postwar era. As the May season approaches, anticipation is building that this Rothko-led offering could set new benchmarks for abstract expressionism at auction—and serve as a fitting tribute to a man who spent a lifetime championing its quiet power.
Sotheby’s full announcement and catalogue previews are available on their website, with global exhibitions and further details forthcoming.
