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 many more. 
 
 Design (lettering) by San Andreas Fault (not credited), medium foil-coated index stock poster is in good to very good (B to B/B+) condition; there are a few tiny stress bends/light creases scattered along the outer margins and within the image area (mostly along the lower margin), a 3" hairline-thin horizontal stress bend in the left/center of the image area and a few stray thin scratches and light scuffs 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).
