The 1st printing matches the stock and color of the postcards, displaying a darker orange than that of the reprints. It measures 14" x 20" and was printed before the concert.
The 2nd printing poster contains a medium blue or darker and was printed alongside the 2nd printing of FD059. The reverse turns gray under black light and is wider than the other two 2nd printings, measuring 14 3/8" x 20 1/16". All reprints are characterized by the presence of a horizontal scratch measuring about 3/8" in the blue border above the "Kepler's Book Store" credit in the ticket outlet strip.
The 2nd printing A contains the horizontal scratch mentioned above. The reverse turns gray under black light, and also has the medium blue. It was also printed next to FD059, but only measures 14" x 20".
The 2nd printing B also has the horizontal scratch, but unlike the other reprints, does not turn gray under black light. Its blue is much lighter than medium blue and measures 14" x 20".
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.
