At the Whitney Museum of American Art in New York there is an exhibit called "Summer of Love Art of the Psychedelic Era." It's fun. Take-away is that San Francisco did the best posters; London and LA had the better photographers. Everyone had interesting music. Great contrast with Bob Dylan headlining in Atlantic City 40 years later...
Here's a 10 second video featuring Janis Joplin's car which is parked in the Whitney yard. Give the link a few seconds to load, otherwise you will just get audio.
