Original 1st printing 19&3/4 x 25&1/8" psychedelic concert/event poster for a Theta Xi Fraternity party held at the Rochester (NY) Institute for Technology Gym on 10/10/1970. Headlining the event were local Rochester bands the Red, White & Blues Band and Mushroom. Designer unknown, medium-thin glossy coated index stock poster is in very good (B/B+) condition; a slight curl to the paper, a few small scattered edge nicks and dings, a small bend in the top left corner tip, assorted tiny surface scratches, stress bends and thin (well-camouflaged) horizontal creases, a pair of tiny stains on the "X" of "Xi" and a couple of very well-hidden pinholes around the outer edges, otherwise fine. Really neat-looking oddball psychedelic poster from upstate New York.
