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 performed), 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/decent (B to B/B-) condition; there are a series of tiny stress bends/creases scattered throughout the image area, along with a couple of tiny areas of "worming", a tiny pull in the bottom right corner tip, a few stray thin scratches and light scuffs here and there, a couple of semi-pronounced diagonal corner/edge bends and a bit of edge wear/creasing along the upper margin area, otherwise OK.
 
 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).
