There are two variations of the pre-concert 1st printing.

1st printing A is on orange/yellow stock and has a bright red ticket outlet strip. It measures 15" x 20" and shows "The Bindweed Press, San Francisco" credit in the bottom right hand corner.

1st printing B is on yellow stock and has a brownish/red ticket outlet strip. It also measures 15" x 20" and has "The Bindweed Press, San Francisco" credit in the bottom right hand corner.

The 3rd printing is on uncoated index with a white reverse. It eliminates the Bindweed credit and adds "(c) Family Dog Productions, 1725 Washington Street, San Francisco" to the left hand side. A "36-3" notation is in the lower right hand corner. The 3rd printing measures 14 1/8" x 20 1/8" and was printed after the concert.

There is no known 2nd printing.

Born in Spain, Victor Moscoso was the first of the rock poster artists with serious academic training and experience. At the Avalon Ballroom in San Francisco, Moscoso saw rock posters and decided that he could "make some money doing posters for those guys." In 1966, he began designing posters for the Avalon Ballroom; and under his own imprint, Neon Rose, a series for the Matrix, a San Francisco nightclub. Moscoso's style is most notable for its visual intensity, which was obtained by manipulating form and color to create optical effects. He used clashing, vibrating colors and deliberately illegible psychedelic lettering to demand attention.
