This December, Sotheby’s Important 20th Century Design auction will present a curated selection of decorative arts and design from the last 100 years. Commencing with masterworks of prewar design, the sale includes many rare offerings from the American Arts & Crafts and French Art Deco periods. The magnificent Coiffeuse and Chair shown here is just one of several masterworks on offer by designer Emile-Jacques Ruhlmann. The sale also presents collectors with a broad exploration of modern and contemporary design, highlighted by this exceedingly rare monumental sculpture of a Centaur by Francois-Xavier and Claude Lalanne.
