Der Prestel Kunstmarkt (2006)

Here is a description of the game from Spielbox:

Der Prestel Kunstmarkt (Art Market) has the subtitle “Gamble, Invest, Win” and is by Franz-Benno Delonge. Which artist will command the highest prices? Which genre is in particularly high demand? Which auctions should be acted on? The ‘art dealers’ in this game must keep the demands of their customers in mind while acting quickly in the art market. He who uses clever tactics and buys low while selling high will win in the end. Der Prestel Kunstmarkt is an engrossing strategy game for 3 to 5 clever dealers with a nose for business as well as the finer things in life.
