Original 1st printing (Bindweed Press credit, yellow background) 13&3/4 x 19&7/8" conference/event poster for the Sierra Club's 10th Biennial Wilderness Conference held at the Hilton Hotel in San Francisco, CA on 4/7-9/1967.

 

 Art by Stanley Mouse and Alton Kelley, image is featured in the Art of Rock book on page 239 (plate 2.365).

 

 Medium flat vellum stock poster is in good/decent (B to B/B-) condition; there is a fair amount of curl to the paper from being tightly rolled, along with a quartet of decent-sized tack holes (one in each corner), a series of semi-camouflaged roll/stress bends hiding within the image area, a few tiny edge tears and little nicks going around the outer margin area, a small stain in the bottom center margin, a light to moderate degree of toning, a small sticker, a bit of flair-pen writing ("Wilderness") and a few soft tape pulls on the re verse... definitely not mint, but not too bad- a fairly decent-looking example overall.
