LONDON.- Sothebys London Impressionist & Modern Art Evening Sale, on Wednesday 22nd June 2011, will offer a selection of works of exceptional quality and rarity, many of which have remained in private collections for decades and have never before appeared at auction. In addition to two exquisite works on one of René Magrittes most sought-after themes, L’Empire des lumières, a monumental Joan Miró and a rare painting by Paul Klee, the sale is led by one of the most important oils by Egon Schiele ever to come to the market, Häuser mit bunter Wäsche (Vorstadt II), being sold by the Leopold Museum, Vienna, and estimated at £22-30 million / $36-50 million. Further important works include a lifetime cast of Alberto Giacomettis bronze Trois hommes qui marchent II (est. £10-15 million) – an instantly recognisable icon of Modern art which forms the genesis of LHomme qui marche I
