On 16 December in New York, Sotheby's will hold a dedicated sale of an interior of furniture by Émile-Jacques Ruhlmann, the legendary French Art Deco atelier. The nine masterworks were commissioned by an American family, and this auction represents the first time in over ten years that such a complete interior of works by Ruhlmann will be offered at auction. Even more remarkable is the archive of documents preserved by the family that outlines the history of the commission. Correspondence with the atelier traces the customizing of each work, bills of sale and original certificates signed by Ruhlmann. The works have been in storage for nearly a quarter of a century, and present an extremely rare opportunity for collectors.
