Original 1st printing 12&3/8 x 12&3/8" concert poster ("Serendipity") for the Carnegie Mellon University 1969 Spring Festival featuring Iron Butterfly and Deep Purple, held on the campus of CMU in Pittsburgh, PA from 5/1-3/1969.

 Designer unknown/not credited (image based on Richard Avedon's 1968 portrait of George Harrison), medium-thin glossy coated index stock poster is in very good to excellent (B/B+ to B+) condition; there are tiny tack/pin holes in the top/bottom center margins, along with a couple of hairline-thin surface scratches and tiny fingerprint smudges scattered around the image area, a couple of tiny corner-tip bumps and a set of tape marks with a light surface pull on the reverse side, otherwise fine. 

 ULTRA-COOL little early-1969 college concert/event poster from western Pennsylvania.
