So you got to watch auctions if you want to invest in art, because that's the only way to find out about this special kind of fashion. I live long enough to have witnessed some shifts already. For example, when I came to Bielefeld, a middle sized city of some 200,000 inhabitants in 1971, they proudly presented a large painting of Georges Mathieu, French abstract painter, at the local Fine Art Museum. It was moved to the depot ten years later and will most probably never show up again. The more you delve into this field the more interesting it gets.
Money is just another name for the desire to find out what is worth which amount.
I tend to rather call that quality. People like to express their feeling of quality in money. To be a player in this field you got to arouse interest in the first place. If you don't play, this doesn't mean you don't produce art. If you do and succeed, this doesn't mean you produce good art either.
