Norton Simon Museum in Pasadena

If you start chronologically, one of the earlier works to look for is Raphael's famous Madonna and Child with Book (c.1502-3). Francisco de Zurburan's Still Life with Lemons, Oranges and a Rose (1633) is one of the most studied pieces in the collection along with Rembrandt van Rijn's Portrait of a Boy, Presumed to Be the Artist's Son, Titus (c. 1645-50).

The Impressionists collection is the most popular part of the museum and it's easy to understand why. Within a few steps, you can see paintings by Matisse, Renoir, Van Gogh, Manet, Monet, Toulouse-Lautrec, Cezanne and Degas, with multiple examples of each. The museum has over 100 works by Edgar Degas, including drawings, paintings, sculptures and the bronze modèles he used as studies for his larger sculptures.

Pablo Picasso was another of the collector's favorites. The museum owns 45 Picasos from early pre-cubist drawings to bronze sculptures and the well-known cubist icon, Woman with a Book. About a dozen pieces by the artist are on display at any one time.
