Collectors behind November's marquee auction lots come into view
Provenance records link a Seagram heir, a Hyatt executive and a private-equity investor to New York evening-sale consignments.
NEW YORK — ARTnews matched anonymous lots in the Christie's and Sotheby's November evening sales to their likely sellers, using catalogue provenance and catalogue raisonné entries. The cover lot of Christie's 20th Century Evening Sale, Kandinsky's Betonte Ecken (1922-23), is estimated at $60 million to $80 million and was consigned by the Nahmad dealing family. Two Surrealist lots point to Clarissa and Edgar Bronfman Jr. A 1968 Rothko on paper (estimate $10 million to $15 million) appears to come from Ed and Jackie Rabin. A Degas drawing belongs to a trust tied to investor Frederick Iseman, whose group also includes works by Seurat, Picasso, Ernst and David Smith. Forty of Christie's 79 lots in the 20th Century sale carry named consignors. The seven Heroes & Lovers lots are widely understood to be Jeff Koons's. The attributions are ARTnews's inferences, not confirmed by the auction houses.
Why it mattersWho is selling, and how many sellers are named, helps show how confident the top of the market is after May's roughly $2.5 billion in sales across the three houses.
