That is what I find most galling about Prince. He is willing, to protect himself and his income stream, to assert the works of another are without artistic merit until he modifies them, after which they are worth millions. He is an amoral scumbag charlatan.
Of course, you've got to wonder what kind of an idiot would separate themselves from a cool couple of million to own one. I don't think much of anyone throwing around that kind of cash to buy that kind of art.
