Original 1st printing 14&/2 x 20" double-sided (contact info on reverse) 1968 promotional poster for Bay Area psychedelic band Initial Shock. 
 
 Art by Joe Gomez, medium flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; there are a series of soft horizontal roll creases traversing image area from the top to the bottom margins, along with a few scattered tiny edge creases along the right margin, a few light handling/stress bends hiding within the image area, a touch of corner tip wear and a bit of uneven toning on the reverse, otherwise fine.

 Nifty-looking late-'60's psychedelic promo poster from the Bay Area.
