A couple of copies of this were lying around the office, and I never knew the story behind this title. Apparently, this was the first official publication from Last Gasp, who ended up being one of the larger underground publishers in the states. This book was started as a promo for one of the first enviromental centers up in Berkeley back in 1970. When the publisher, Ron Turner, had 20,000 copies left over that he couldn't give away, he decided to sell them in stores, and thus, the Last Gasp story began.
A slew of artists and writes made there way through the series, the likes of Gilbert Shelton, Jack Jackson and Ben Dicaprio (yeah, THAT DiCaprio). The series petered out in the late 70's, early 80's, the company would go on the publish some of the best underground titles since and remain on of the biggest independent publishers around.
