Van Gogh, Cezanne, and Picasso were Europeans, and Europe is where art speculation and the "Art Market" was born, and where Art History became equated with Art Market History. Americans showed up with a 20 year lag and kept lagging, with e.g. Pollock imitating Picasso in the 1940s. By then, globally-viral-Picasso was selling paintings for hundreds of thousands of inflation adjusted dollars.
