These glamorous panels - so redolent of the interiors of the 1930's and 1940's - are reputedly from the collection of Helena Rubinstein. Rubinstein, who founded the eponymous cosmetics firm, was one of the wealthiest women in the first half of the 20th century and a great arbiter of taste. She had a long relationship with the equally august decorating form of Maison Jansen - who designed interiors for both Rubinstein's Paris apartment and the Moulin de Breuil in Combs-la-Ville outside of Paris (see S. Slesin, Over the Top: Helena Rubinstein Beauty, Art, Fashion, Design, New York, 2003, pp. 116-117, for example). And while the panels cannot be conclusively attributed to Jansen, they relate closely to many of the interiors as well as individual pieces of furniture Jansen designed. The use of gilt-etched glass was a particular trademark and one of the best examples are the mirrored architectural elements used in the fiercely modern château Solveig built in the mid-1930's on the shore of Lake Geneva.
