By early 1906, Leo and Gertrude Stein's studio had many paintings by Henri Manguin, Pierre Bonnard, Pablo Picasso, Paul Cézanne, Pierre-Auguste Renoir, Honoré Daumier, Henri Matisse, and Henri de Toulouse-Lautrec. Their collection was representative of two famous art exhibitions that took place during their residence together in Paris, and to which they contributed, either by lending their art or by patronizing the featured artists. The Steins' elder brother, Michael, and sister-in-law Sarah (Sally) acquired a large number of Henri Matisse paintings; Gertrude's friends from Baltimore, Claribel and Etta Cone, collected similarly, eventually donating their art collection, virtually intact, to the Baltimore Museum of Art.
