Sotheby's will offer the collection of cable television magnate Ted Baum and his wife, interior designer Ruth Baum, with the whole expected to total more than $100 million. More than 130 works will be sold, beginning with a dedicated evening auction on November 16, a day sale on November 17, and further offerings in sales throughout next year. Highlights will go on public display in London, Hong Kong, Paris, Los Angeles and New York. The sale is led by a Mark Rothko painting on paper estimated at $10-15 million and an Ed Ruscha painting carrying the same estimate. A Joan Mitchell canvas, Green Book of Barbara Guest (1960), is estimated in the region of $12 million, while works by Alberto Burri, Lucio Fontana and Andy Warhol are each tagged at $4-6 million. The remainder of the collection, which includes Roy Lichtenstein, Yves Klein, Piero Manzoni, Tom Wesselmann and David Hammons, has yet to be assigned estimates. The Baums' advisor, New York's Wendy Cromwell, said the couple knew what they liked, were insatiably curious and kept pushing their eye, producing a collection that gallops through time, countries and genres. Their holdings tell the story, she said, of what it means to collect contemporary art. Ted Baum died in 2021 and Ruth followed this year. The couple kept homes in New York, New Jersey, Southampton and Palm Beach, Florida, and were active philanthropists: a gallery at the Norton Museum of Art in West Palm Beach is named for them, they funded the institution's first contemporary art curator position, donated works by Dale Chihuly and Leo Villareal, and served on boards and committees at New York's Guggenheim Museum and the Parrish Art Museum.
