I will be checking this account then @symbolism
A few years ago I was an avid reader of vigilantcitizen, where they put analysis of movies and music based on their symbolism. I read a lot of crazy stuff in there, because they were more about the conspiracy side of symbolism.
About the art ... what can we say. There is a famous french movie called The Intouchables and there is a scene where the millionaire guy manage to sell a simple painting from his poor friend for several thousands $. Only because he had good contacts. And perhaps in real life it is the same, regular art is "worth" millions, simply because the painter has good contacts.
