Sotheby’s is thrilled to announce the forthcoming landmark sales of The Macklowe Collection — one of the most important collections, of any kind, ever to come to the market. Each of the 65 Modern and Contemporary art works is a consummate masterpiece in its own right; together they constitute an unrivalled ensemble that charts the highpoints of Western artistic achievement of the last 80 years. Estimated to realize in excess of $600 million — the highest estimate ever placed on any collection to come to auction — The Macklowe Collection will be offered across two dedicated evening single-owner sales at Sotheby’s in New York, on November 15 this year, and in May 2022. The first of the two sales will feature 34 works which together encompass an extraordinary breadth of 20th- and 21st-century art, ranging in date from the 1940s to works painted less than a decade ago, and including masterworks by Alberto Giacometti, Mark Rothko, Cy Twombly, and Andy Warhol. The sale will also shine a light on a distinguishing feature of the collection as a whole: its enormous depth. Many artists – among them Jeff Koons, Brice Marden, Agnes Martin, Sigmar Polke, Gerhard Richter, Cy Twombly and Andy Warhol – are represented by multiple works, each one marking a distinct and critical moment in their respective careers, and together forming an insightful portrait of the artists’ evolution over time. Highlights from the collection will be available to view in Sotheby's New York galleries 9-12 September and will then be exhibited around the world until 15 November.
