An article discusses the market for autographs by Mickey Mantle, the superstar centerfielder for the New York Yankees during the 1950s and 1960s: "At card shows, golf outings, charity dinners, Mr. Mantle signed his name over and over." One expert on sport autographs is quoted as saying: "He was a real good signer ... He is not rare." Yet the article quotes another expert as saying: "Mr. Mantle's autograph ranks No. 3 of most-popular autographs, behind Babe Ruth and Muhammad Ali." A baseball signed by Mantle is likely to sell for the relatively high price of $250 to $400. By contrast, baseballs signed by Whitey Ford, a teammate of Mantle's on the Yankees, typically sell for less than $150. Source: Beth DeCarbo, "Mantle Autographs Not Rare, but Collectors Don't Care," Wall Street Journal, August 4, 2008. Explain how the price of baseballs signed by Mantle could be higher than the price of baseballs signed by Ford. The supply curve for baseballs signed by Mantle should be an upward-sloping line that is to the __________ of the supply curve for baseballs signed by Ford. In order for the price of baseballs signed by Mantle to be higher than the price of baseballs signed by Ford, the demand curve for baseballs signed by Mantle must be a downward-sloping line that is
right significantly to the right of the demand curve for baseballs signed by Ford.'
