Starry Night by Vincent Van Gogh. This painting depicts the view outside Van gogh's sanitorium room window at Saint-Rémy-de-Provence, at night. Made even more famous by singer, Don McLean's 1971 song, 'Vincent' (Starry, Starry Night).
Van Gogh's Starry night is my favorite painting. But once I read his biography, it made me so sad that I gave the print of the painting to my husband for his office. Now I just hang my second favorite, French painter Monet's Waterliles.
