As a rule of thumb, 8% annualized net return over a minimum holding period of five years is a realistic figure. Pablo Picasso's 1905 portrait 'Boy with a Pipe' sold for $104.2 million in an auction at Sotheby's Holdings, Inc., on June 24, 2004, shattering the existing record for art and ushering in a new era in pricing for the 20th-century paintings. The Picasso, sold by philanthropic Greentree Foundation, cost Mr. Whitney about $30000 in 1950. Determine the annual rate of appreciation of the artwork over 54 years. Is this a good investment?
