I personally don't like his work but in all honesty he is one of the most important American artists of the 20th century. His work might not be sold in high art galleries but a lot of his work is hanging in living rooms making people smile or feel good. His work says more about the public art taste of 20th and early 21st century than any work by any other contemporary artist save Anne Geddes. Art critics and artist might dislike him but he created art for the masses as opposed to art for a few.
