Lois Wagner Fine Arts, Inc. is a Manhattan-based private art dealership founded and led by Lois Wagner, who has specialized for more than thirty years in nineteenth- and twentieth-century American and European art, including paintings, works on paper, and sculpture. Operating by appointment rather than as a walk-in gallery, the firm serves as a private and corporate curator, dealer, and advisor, and has facilitated acquisitions and sales of works by artists including Mary Cassatt, William Merritt Chase, Childe Hassam, Robert Henri, and Henry Ossawa Tanner, among others. Beyond sales, the firm offers appraisal, framing, restoration, installation, estate liquidation, and scholarly research services to a limited roster of clients, collectors, and institutions.
