Founded 200 years ago, Annibale Colombo makes fine reproductions as well as updated versions of antiques. Many of the traditional pieces are designed in antique English and French styles; the more transitional designs are simplified versions of neoclassical pieces. Regardless of style, all of Annibale Colombo’s furniture is made from solid wood using traditional techniques, then decorated with veneer. (Sixty different wood species are used for veneering.) The company, which is based in Novedrate, produces a complete line of furniture, ranging from beds and sofas to shelving units. The collection is sold in a handful of US stores.
Jan Showers in Dallas, Texas is the best antique dealer; they specialize in 1920s to 50s French furniture and accessories, and some Italian.
I love Cedric Dupont's antique shop in West Palm Beach. They have a great collection of 18th and 19th century French and Italian antique furniture and accessories. There's also a shop in Southampton, New York.
