Original 1st printing 8&1/2 x 11&5/8" concert flyer for Country Joe & the Fish appearing at Pauley Ballroom on the campus of the University of California in Berkeley, CA on 1/28/1967
 
 Artist unknown/not credited, thin flat stock flyer is in excellent (B+) condition; there is a small pronounced  1" horizontal pressure crease/bend along the upper left margin and a few soft handling dings here and there, otherwise it is a VERY sharp example of this nifty-looking little Country Joe & the Fish concert artifact from the East Bay.

 First one of these I have ever offered up!
