Original 1st printing 13&1/2 x 23&3/4" concert poster for the San Francisco Palace of Fine Arts Festival, a three-day concert/event held at the P.F.A. in San Francisco, CA from 8/30-9/2/1968.

 No acts are listed on the poster (and it's not known exactly who did and didn't show up), but the participants listed in the program include: Grateful Dead, Santana, Quicksilver Messenger Service, Sons of Champlin, San Francisco Mime Troupe, Steve Miller Band, Kaleidoscope, Big Mama Thornton, H.P. Lovecraft, Ace of Cups and others.
 
 Design (lettering) by San Andreas Fault (not credited), medium-thin foil-coated index stock poster is in very good (B/B+) condition; there is an approximately 5" thin vertical/diagonal stress bend along the lower left margin/edge, plus a 1/2" bend in the lower left corner tip and a few stray thin scratches and fingerprint smudges here and there, but overall it's a pretty nice example.
 
 Neat-looking silver foil multi-day event poster from San Francisco, the program listing (same image with show information, in different colors) can be seen in the Art of Rock on page 205 (2.237, 2.238 & 2.239).
