The Post-Impressionists are Still Alive & Well

They're the rock stars of the art world and still drawing massive crowds everywhere around the world.  It's easy to understand when you're standing before a masterwork by Paul Gauguin, Paul Cezanne, Vincent van Gogh, Edgar Degas, Toulouse Lautrec...  I wonder how they'd feel to know how popular they are in the 21st century and to see how much their images have been commercialized.
