Original 1st printing 17&1/2 x 22&1/2" art exhibit poster for the 9/29/1967 opening of "Postpsychedelic Art", a multi-artist show held at the One Eleven Gallery on St. Mark's Place in New York City.
 
 Art by Martin Carey,  The image is Exorcise The Pentagon.
 
 Medium-thin flat vellum stock poster is in good/decent (B to B/B-) condition; there are a pair of soft quarter-sized oil stains in the lower left/right corners, along with a couple of tiny edge/corner creases/nip tears in the lower left corner, a few soft handling dings here and there, a pair of vertical scuffs in the lower right margin, a few tiny edge creases/nip tears scattered around the outer margin area and a trace of edge toning, otherwise fine.
Neat-looking late-'67 oddball psychedelic art exhibit piece from the East Village.
