Christies New York Design, December 12
This sale includes over 150 lots across all Design movements of the 20th Century. Highlights include a window by Tiffany Studios (see image above), two sets of rare chairs by French Art Deco designer André Sornay, a pair of wrought iron gates by Edgar Brandt and a desk by Émile-Jacques Ruhlmann.

Tiffany’s 1902 ‘Snowball and Wisteria’ window is a masterpiece to showcase Louis Comfort Tiffany’s admiration of nature. Tiffany had an extensive knowledge of flowers, and used floral decorations in the most elaborate way throughout his work. Tiffany’s leaded glass windows were designed to create transparency between interior and exterior space. According to Tiffany’s daughter Louise Comfort Guilder, this window was a favorite of her father.

Phillips New York Design Evening Sale, December 13
The focus in this 47-lot sale of 20th century design lies in its showcase of French and Italian designers, mixed with very important American pieces. Highlights of the sale include works by Carlo Mollino, Gio Ponti, Marcel Coard, and Isamu Noguchi.

Two extraordinary works by Carlo Mollino lead the sale: a ‘specchio-armadio,’ a signature installation of Mollino’s consisting of a console, a mirror, and an adjustable sconce. The specchio, as well as a set of lounge chairs that are also in the sale, were commissioned by Ada Cesare for her home in Turin, Italy, between 1944 and 1946 and have remained in her home ever since. Cesare encouraged Mollino to express his artistic vision with those designs and reflect a breakthrough in his career. Also in the sale are drinks cabinet by Marcel Coard, and a sideboard by master collaborative duo Jean Dunand and Eugène Printz.
