Van Gogh operates an art gallery. He has several paintings from unknown artists that he has listed for sale. The paintings always sell at his weekly auction for $30,000 - $60,000 above what Van Gogh believes them to be worth. Van Gogh learns that the bidders at the auctions are employed by Corleone Olive Company, an olive distributor, located near the shipping yards of the city. What concerns should Van Gogh have about the art, the bidders, and the large purchase prices?
