Macklowe Gallery is the world's premier dealer of museum-quality Twentieth Century Decorative Arts and Antique and Estate Jewelry. For over 40 years we have specialized in French Art Nouveau furniture and objects, Tiffany lamps and Tiffany glass, French cameo glass by Argy-Rousseau, Daum and Gall?, bronzes, ceramics, lithographs by Alphonse Mucha, and antique and estate jewelry. Since 1971, when we opened our first store on Madison Avenue, scholars, museum curators, and collectors have sought us out to find the best our period has to offer. Each piece in the Gallery is authentic, and chosen for its artistic value, rarity and historic importance. With over 5,000 square feet of space, we are able to display the most important and comprehensive collection in the world.
