Original 1st printing (Bindweed Press credit, yellow background) 14&1/4 x 19&7/8" (untrimmed left margin) 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 (and SIGNED in gold pen by) Stanley Mouse (with 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/B-) condition; the main issue with this example is a large horizontal black ink streak (about 3&1/2" long at its widest) extending from the upper left margin into the image area, where it thins out into a thin line that traverses the center of the image area almost to the right interior border of the central image; besides that, there are tack/pin holes in all four corners, a few light handling dings and hairline-thin stress creases scattered throughout the image area, a bit of edge toning and a few stray tiny edge tears/nicks scattered around the outer margin area, otherwise fine.

 

 Decent-looking ARTIST-SIGNED example of this classic Mouse/Kelley image from the AOR.
