First print original poster advertising a show on June 20th - 23rd 1968 at the Carousel Ballroom San Francisco, CA. Featuring Big Brother & the Holding Company, Fleetwood Mac and Dr. Poster in near mint condition. I very rarely post posters as mint.
However this poster is about as close as you can get. I doubt it would be possible to find one in better condition Handbill is in near mint minus condition with a bit of yellowing on the right side.
