Sotheby’s announces some highlights from the November Impressionist and Modern sales. The van Gogh is the headliner with several other works from the Franck family, including three James Ensor paintings.

Vincent van Gogh’s Paysage sous un ciel mouvementé (estimate $50/70 million) is a sweeping landscape view from Arles dating to the artist’s coveted mature period, which will lead an exquisite group of late-19^th and early-20^th century masterworks assembled in the 1940s and ‘50s by Belgian collectors Louis and Evelyn Franck. The Francks’ distinguished collection also offers: Pablo Picasso’s Nu au jambes croisées, a large-scale, fully-worked pastel from his famed Blue Period (estimate $8/12 million); superb examples by Paul Cézanne, Kees van Dongen and Henri de Toulouse-Lautrec; and the finest work by Belgian painter James Ensor ever to appear at auction.
