Although while living in Paris, he had met and studied the paintings of Claude Monet, his work is generally closer to that of Georges Rouault and Pablo Picasso.
His circle of acquaintances included Paul Signac, Émile Chartier, Charles Vildrac, Georges Duhamel, Jules Romains, Georges Rouault, and Jean Cocteau and partially supported himself by sending their works to Japan.
When John Kraushaar, Charles's younger brother, joined the business the gallery also began showing modern French painters: Soutine, Matisse, Roualt, Modigliani, Redon, Picasso and other late 19th- and early 20th-century artists.
His collection focused on 19th- and 20th-century artists including Paul Cézanne, Jean-Baptiste-Camille Corot, Edgar Degas, Paul Gauguin, Juan Gris, Paul Klee, John Marin, Henri Matisse, Amedeo Modigliani, Claude Monet, Georgia O'Keeffe, Pierre-Auguste Renoir, Georges Rouault and Georges Seurat.
