Comic book fans eagerly compete to buy copies of Amazing Fantasy No. 15, which contains the first appearance of the superhero Spider-Man. At the same time the publisher printed copies of the comic for the U.S. market, with the price printed on the cover in cents, it printed copies for the U.K. market, with the price printed on the cover in British pence. About 10 times as many U.S. copies of Amazing Fantasy No. 15 have survived as U.K. copies. Yet in auctions that occurred at about the same time, a U.S. copy sold for $29,000, while a U.K. copy in the same condition sold for only $10,755. Use a demand and supply graph to explain how the U.S. version of the comic has a higher price than the U.K. version, even though the supply of the U.S. version is so much greater than the supply of the U.K. version?
