Country Joe & the Fish Poster
The 1st printing A is on thin coated glossy stock, matching the postcard of the same name. It reflects a bright blue background, measures 14 1/4" x 19 7/8" and was printed before the concert.
The 1st printing B is on thicker, coarser stock, which is a bit duller than the A version. It measures 14 1/8" x 19 15/16" and was also printed before the concert.
The post-concert 2nd printing is on plated smooth stock. The moons range in color from light green to dark green. In the top left corner, there is a faint black line about 1/2" above the top left star. It is about 5/8" long and is only on the post-concert reprints. Sizes vary slightly due to being printed two-up and not getting cut directly in the middle of the paper. Measurements range from 14" x 20" to 14 3/16" 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.
