New marketing techniques were applied to stimulate the demand for art, and efforts were made to increase ex- ports. The printed auction catalogue and advertisements in newspapers announcing upcoming art sales in many ways revolutionized the market. Furthermore, it is as- sumed that foreign dealers frequently traveled to Dutch and Flemish cities to buy up local art, hoping to resell these prized goods for a profit in Paris, London or at the German courts. Seen from this perspective, it can be argued that this time period witnessed the beginnings of a more integrated European art market. The Low Countries were at the heart of these developments, and their art centers played a pioneering role in introducing innovations in the marketing of art, such as specialized art auctions. We therefore intend to explore Weyer- man’s writings in search of meaningful and previously unrecognized observations concerning the state of the art market.
