Artcurial will offer the collection of Louis Grandchamp des Raux, A Shared Modernity, at auction in Paris on 24 October, timed to coincide with Art Basel Paris week. Assembled over twenty years, the group brings together nearly seventy-five works by forty-four artists and traces the major movements of French and Belgian painting from the late 19th century to the mid-20th. The leading lot is Maurice Denis's L'Ile Chevalier, painted in 1894 and estimated at €700,000 to €1,000,000. Pierre Bonnard's La petite fenetre carries an estimate of €550,000 to €750,000, while Edouard Vuillard's Misia Natanson dans les bois is estimated at €450,000 to €650,000. Jean-Francois Millet's Barque de peche, from around 1870-71, is expected to make €500,000 to €800,000. The collection opens with pioneers of plein-air painting, including Theodore Gericault and works by Corot, Courbet and Boudin, then moves through Impressionism — represented by two Berthe Morisot canvases — into Symbolism, the Pont-Aven School and the Nabis, before arriving at the chromatic freedom of Bonnard. Works by Henri Martin, Armand Guillaumin and Henry Moret further explore the relationship between landscape and color. Timed alongside Art Basel Paris, the sale is positioned as one of the marquee single-owner offerings of the French autumn season. Artcurial describes the collector's eye as at once exacting and sensitive, and the presentation emphasizes how masterworks and rediscoveries sit side by side within a single coherent vision of modernity. The evening sale follows Artcurial's other Art Basel Paris week auctions, including its ceramics sale on 23 October and the Selected 20/21 modern and contemporary auction on 24 October, making the Paris week a concentrated moment for the house's art departments.
