Artcurial will offer the Louis Grandchamp des Raux collection at auction on October 24, 2026 at 4pm at Artcurial Beurret Bailly Widmer in Geneva. The sale brings together nearly seventy-five works by forty-four artists spanning Impressionism to Symbolism, the Nabis and the Pont-Aven School. Top lots include Maurice Denis’s Misia Natanson dans un bois, estimated at €700,000–1,000,000, Pierre Bonnard’s two paintings estimated at €550,000–750,000 and €150,000–250,000, and Édouard Vuillard’s work estimated at €450,000–650,000. Additional highlights feature Théodore Géricault’s Barque de pêche, circa 1870-1871, estimated at €500,000–800,000, and Fernand Khnopff and Léon Spilliaert pieces each estimated at €300,000–400,000.
The Signal
The collection reflects a collector’s focused shift since 2010 toward late-19th-century French and Belgian modernism after an earlier phase devoted to 17th- and 18th-century works. Its dispersal follows the 2015 sale of Grandchamp des Raux’s earlier holdings and signals continued market demand for Nabis and Pont-Aven material at the upper-mid price tier. Viewings run in Geneva from October 19 to 24 and earlier in Zurich and Basel, giving regional collectors direct access before the single-session evening sale.
