The gallery presents a carefully curated selection of works of art spanning the period from 1890 to the present day. An accredited expert with the FNEPSA (Fédération Nationale d'Experts Professionnels Spécialisés en Art), Agnès Aittouarès established her own appraisal and advisory practice in 2020, dedicated to modern and contemporary art.
