There is a tale, perhaps apocryphal, of a posse of
wealthy collectors turning up, only to find that as they waited the artist had sneaked up behind them and urinated down the backs of their coats.
In
turn, this led to: more demand for urban architecture; more demand for applied art and design - see, for instance the Bauhaus School - and the emergence of a new class of
wealthy entrepreneurs who became art
collectors and patrons.
