Owner produces several letters and receipts showing that the drawing is authentic and Owner believes that it is, in fact, an original.Collector agrees and offers $10,000 for the drawing and Owner accepts.The next day, Collector returns to the Gallery with a cashier's check in the amount of $10,000 and accompanied by his Daughter, a recent graduate from FSU with a MFA in modern art.Daughter takes one look at the drawing and says, "It's a fake. There are hundreds of these on the market that were drawn by foreign copy cats in the 1990's." Daughter is, in fact, correct.
