Painted in 1922 during one of Henri Manguin's extended sojourns on the French Riviera, Jeanne sur la plage de l'Oustalet captures his wife and lifelong muse in a moment of sun-drenched repose along the Mediterranean shore. The composition radiates the chromatic intensity that defined Manguin's mature practice, with warm flesh tones set against shimmering blues and greens that dissolve the boundary between figure and landscape. His brushwork is confident and sensuous, translating direct observation into a surface alive with optical vibration, a quality that positioned him as one of the most accomplished colorists to emerge from the Fauve circle. Manguin spent formative years alongside Matisse, Marquet, and Derain in Moreau's studio and exhibited at the landmark 1905 Salon d'Automne that introduced Fauvism to the world, yet his career has long rewarded closer attention from collectors who look beyond the movement's most celebrated names. Works featuring Jeanne hold particular significance within his oeuvre, as she appears across decades of painting as both intimate subject and compositional anchor, lending this canvas a biographical resonance that deepens its pictorial appeal. The relatively intimate scale of 38 by 46 centimeters concentrates the painting's energy without diminishing its presence, making it well-suited to refined domestic interiors. Offered through Galerie Ludorff and presented in its original frame, the work arrives in a condition consistent with its age and provenance. The oil on canvas mounted on cardboard support is characteristic of Manguin's plein air practice during this period, when portability served his commitment to working in natural light. For collectors drawn to early twentieth century French modernism, this signed canvas represents a rare opportunity to acquire a deeply personal work from one of the movement's most gifted yet still undervalued practitioners.
