A psychedelic 1964 Porsche once owned by rock legend Janis Joplin fetched $1.76 million, versus the estimated presale range of $400,000 to $600,000.  Joplin bought the car in 1968 for $3,500 and drove it daily, often accompanied by her dog, according to the catalog. The surface is hand-painted with California landscapes, Zodiac signs, smoke and portraits of the Big Brother and the Holding Company band members. Since 1995, the car has been on loan at the Rock and Roll Hall of Fame and Museum in Cleveland.
