Original 1st printing 17&1/2 x 23" concert poster for folk singer Patrick Sky appearing with Mt. Rushmore and Clover, (*plus Mad River, Freedom Highway and the Dossier (a play by Tadeus Rosewicz), not listed) at the Straight Theater in San Francisco, CA from 8/11-13/1967.

 Art by Bob Harwayne, medium-thick glossy stock poster is in good/decent (B/B-) condition; there are tack/pin holes, a few tiny bends/creases and minor wear in all four corners (with a tiny nip out of the bottom left corner), along with a tack hole/drag tear in the bottom center margin, a light to moderate amount of surface wear, a tiny stray pin-prick burn hole in the upper left corner, a few light handling/stress creases here and there and a series of light surface smudges/stains on the reverse, otherwise fine.

 VERY psychedelic mid-'67 Straight Theater concert poster with a great design and eye-searing colors.
