I found a little history on the car: In September 1968, the budding rock star paid a Beverly Hills auto dealer $3,500 for the three-year-old sports car. When she bought it, the Porsche was a factory-painted “oyster white.” For a flamboyant singer who wore rose-colored glasses and feather boas, that wouldn’t do. So she got roadie Dave Richards to paint it with swirling psychedelic images, including Mount Tamalpais on one fender and a portrait of her with her band, Big Brother and the Holding Company, on another.

The singer’s 1965 Porsche 356c Cabriolet, which she bought when she was living in Larkspur, is usually enshrined in the Rock and Roll Hall of Fame in Cleveland. It came to Marin from the Grammy Museum in Los Angeles, where it was on loan.

“They used regular house paint,” Michael Joplin recalled. “They were just playing around, saying, ‘Hey, let’s make an art car.’ They were having a lot of fun. It was a convertible, and she would drive it around with the top down. People would leave notes for her on it.”

Great detective work there! I guess I had always assumed Peter Max did it. I know he did a couple custom painted guitars for Eric Clapton, and it looked like a similar style to this.
