How can you tell a real Keith Haring painting?

To tell a real Keith Haring painting, examine its details closely. When painting, Haring was able to produce figures and shapes with a single, continuous line. This technique is very hard to duplicate, so most reproductions will show broken, multiple lines. You can also compare the artist's signature to images available on trusted online resources. Since convincing fakes do exist, experts generally recommend that you have a certified art appraiser authenticate your piece rather than attempt to do so on your own.
