NEW YORK, NY.- The Winter Antiques Show finished its first week with strong sales and interest among buyers, including established collectors, design professionals and first-time buyers. Sales were robust across all disciplines, including Americana, antiquities, and 20th century fine and decorative arts. All net proceeds from sponsors, special events, and ticket sales support East Side House Settlement, a non-profit in the South Bronx providing social services to community residents. Among the 20th c. works purchased were a remarkable series of three untitled Alexander Calder standing mobiles, never before seen on the market, and sold as a series by Jonathan Boos to a single collector on opening night. Boos also sold four Calder brooches, also new to the market. At Moderne Gallery, a pair of Wharton Esherick wagon wheel chairs were sold, as well as two Picasso vases and a plate by Peter Voulkos.
