Original 1st printing 14&1/4 x 20&3/4" concert/event poster, "Pow-Wow" (a Gathering of the Tribes/Human Be-In), held at the Polo Grounds in San Francisco's Golden Gate Park on 1/14/1967.
 
 This version lists appearances by Lenore Kandel, Timothy Leary, Michael McClure, Allen Ginsberg, Gary Snyder, Richard Alpert, Jerry Rubin, Dick Gregory, Lawrence Ferlinghetti, Robert Baker, "Buddha" and "all San Francisco rock bands" (which included Jefferson Airplane, Quicksilver Messenger Service, the Charlatans, the Grateful Dead and more).
 
 Art by Rick Griffin, image is featured in the Art of Rock on page 197 (plate 2.215).
 
 Medium-thick flat vellum stock poster is in used (B-) condition; as the photo shows, there are a couple of fairly prominent/large areas of uneven toning along the right/bottom margins, along with a bit of horizontal/diagonal creasing in the lower right corner/margin, a few stray thin bends, handling/stress creases and light smudges hiding within the image area, a few tiny edge nips/dings scattered around the outer margin area, a large horizontal bend traversing the lower portion of the image area and a bit of light surface dirt, otherwise OK.

 While not at the top of the conditional heap, this example is still totally intact with no major rips/holes and pretty decent paper stability- it might clean up nicely if sent to restoration, but I'll leave that up to the winner.
