14 May 2026 | New York | full auction details

This May, Sotheby's New York is honored to present Robert Mnuchin: Collector at Heart. A thoughtfully assembled collection of Modern and Contemporary masterworks, this collection encompasses some of the most significant examples created by the artists Robert Mnuchin championed during his life as a dealer, advisor and collector. Led by pivotal Abstract Expressionist masterworks by Mark Rothko, Willem de Kooning and Franz Kline, the works Robert and Adriana collected reflect a true continuity in vision and instinct. Presented as a standalone single-owner auction during Sotheby’s spring Marquee sales in New York, followed by selections in the Modern and Contemporary Day Auctions, Robert Mnuchin: Collector at Heart reflects Mnuchin’s inimitable sophistication of taste and indefatigable conviction when pursuing works of the highest quality.
