Art and money never touch. They exist in parallel universes of value at comparable levels of cultural generalization: Art does nothing to money but translate it. Money does nothing to art but facilitate its dissemination and buy the occasional bowl of Wheaties for an artist or art dealer. Thus, when you trade a piece of green paper with a picture on it. signed by a bureaucrat, for a piece of white paper with a picture on it, signed by an artist, you haven’t bought anything, since neither piece of paper is worth anything. You have translated your investment and your faith from one universe of value to another.
