Like the sun shining in through your window, sunflower posters and prints are guaranteed to spread cheer in any room. These large, vivid yellow flowers are a brilliant representation of the summer sun. To brighten any space, simply hang a sunflower poster or print by one of your favorite artists. Sunflower posters are the finishing touch that your farmhouse or bohemian space craves. For sunflower prints by famous artists, look for any of Post-Impressionist artist Vincent van Gogh’s beloved "Sunflowers, c. 1888" series, Gustav Klimt's "Farm Garden with Sunflowers," or Georgia O'Keeffe's "Sunflower, New Mexico, c. 1935."
