Consignors Revealed: The Mystery Sellers Behind the $1.8 Billion May Auctions

Sotheby's kicked off the May auction season with a $433 million sale, including an 11-lot group from the estate of late dealer Bob Mnuchin, led by an $86 million Mark Rothko painting. The three major auction houses are offering $1.8 billion worth of art by low estimate, a 50% increase from last year, driven by consignments from estates of key figures like Mnuchin, philanthropist Agnes Gund, and dealer Marian Goodman. Christie's will stage a sale from publisher S.I. Newhouse's collection expected to bring $450 million, potentially setting records for Jackson Pollock and Constantin Brancusi. The article reveals that many top sellers are anonymous, but unmasked names include the Dennison family and French collector John Sayegh-Belchatowski.
