Perhaps they do. Maybe some people just like velvet Elvis or dogs playing poker. A fool and his money are soon parted, but don't go around claiming it's "fine art." It's a canvas reprint that Kinkade's lackeys "handtouched" and then stamped his signature on before charging $1500. Its resale value is about $250 and that's including the frame.
As one of my teachers told me, "It's worth what people will pay for it." Kind of like a stock. Kinkade paintings were a bubble market that popped.
