Original 1st printing 11 x 14" concert poster for Country Joe & the Fish appearing at Woolsey Hall on the campus of Yale University in New Haven, CT on 5/26/1968 (*Art of Rock misidentifies the year as 1971).

 

Artist unknown/not credited, image is featured in the Art of Rock book on page 306 (plate 3.168). 

 Medium flat index stock poster is in good to very good (B to B/B+) condition; there are a series of semi-pronounced thin creases, tiny stress bends and a few stray pin/tack holes scattered around the image area/borders, along with a 1" tear in the upper right margin and a few stray pin-prick stains and light scuffs here and there, otherwise fine. 

 ULTRA-uncommon low-run/oddball Country Joe concert poster from the Art of Rock, this is the first one of these I've had to offer.
