The 1st and 2nd printings are identical and there is a considerable amount of ink variation among both printings, so the colors, particularly in the ticket outlet strip information, range from blue to green, though that does not denote different printing. Both printings are 14 1/8" x 20" on vellum with "The Bindweed Press San Francisco" in the bottom left corner, and both are considered pre-concert originals.

The post-concert 3rd printing, so named because distinguishing features to identify a 2nd printing are lacking, is 14 1/8" x 20 1/2" on uncoated index and notes "No. 23-3" in the lower left corner. "(c) Family Dog Productions 1725 Washington Street San Francisco" is in the lower right corner.

Born in Detroit, Stanley Miller became known as "Mouse" after illustrating countless notebooks with his signature rodent sketch. Miller found an outlet for his creativity in pin-striping cars and airbrushing hot rod designs on posters and T-shirts. Mouse migrated to San Francisco in 1964, where he first met the artists associated with Family Dog, the organization producing dance concerts at the Avalon Ballroom. With collaborator Alton Kelley, Mouse experimented broadly with composition, lettering and imagery: Kelley came up with the ideas and Mouse executed the designs. Mouse and Kelley helped to establish the psychedelic style of expression under the name Mouse Studios.
