Original 1st printing  20 x 13" concert poster for Santana appearing at the Greek Theatre on the campus of the University of California in Berkeley, CA on 9/8/1979.

 Designer unknown/not credited, image is featured in the Art of Rock on page 356 (plate 4.69)

 Medium-thick flat index stock poster is in near mint (A-) condition; really nothing more than a tiny smudge in the right margin and a slight curl to the paper, otherwise it is a VERY sharp/clean example of this oddball late-'70's AOR poster from the Greek Theatre- the only BGP poster I have ever seen with all of the show information en español.
