Original 1st printing 17 x 23" 2-color (red/blue) untrimmed printer's proof sheet of a 1968 promotional poster for Bay Area psychedelic band Initial Shock. 
 
 Art by Joe Gomez, medium-thick flat vellum stock proof is in excellent (B+) condition; the registration is misaligned and there are a couple of tiny pin-prick spots/stains and a few ultra-tiny edge nips in the upper right margin along with a few light handling dings here and there, but overall it is in pretty nice shape.

 Unusual late-'60's oddball psychedelic promo poster from the Bay Area.
