The collection of Robert F. and Patricia G. Ross Weis, assembled over more than 50 years, will be offered at Christie’s 20th and 21st Century Art auctions in New York this November. The collection features major works by modern masters including Rothko, Picasso, Matisse, Mondrian, and Miró, reflecting the couple’s intellectual rigor and shared passion for modernism.
This sale matters because it represents a carefully curated, lifetime collection that traces the evolution of modern art across movements and continents, offering a rare opportunity for the market to acquire iconic works from a single, cohesive private collection. The auction will test demand for top-tier modernist pieces and may set benchmarks for comparable works by these artists.
