Sotheby's is holding its most ambitious May auction series in New York, headlined by Mark Rothko's monumental painting *Brown and Blacks in Reds* (1957), estimated at $70–100 million. The sales include a dedicated auction for the collection of legendary dealer and collector Robert Mnuchin, valued at over $130 million, featuring works by Rothko, Franz Kline, and Jeff Koons. Other highlights include Jean-Michel Basquiat's *Museum Security (Broadway Meltdown)* (1983), estimated at over $45 million, and Willem de Kooning's *Untitled III* (1975), making its auction debut with a $25–35 million estimate. The series spans Modern and Contemporary art, with additional works by Pablo Picasso and Vincent van Gogh.
This auction series matters because it tests the high end of the art market amid fluctuating global economic conditions. The Rothko painting, one of only 15 monumental canvases from 1957, and the Basquiat, from his most coveted period, represent benchmark prices that signal collector confidence. The Mnuchin collection sale also underscores the enduring influence of top-tier dealers in shaping art historical narratives and market values. Results will be closely watched as a barometer for the broader art market in 2025.
