Original 1st printing 14 x 19&7/8" concert poster for Chicago blues legend Otis Rush appearing at the Matrix in San Francisco, CA from 2/28-3/2/1967.
Art by Victor Moscoso with a photo by Paul Ubac, image is # 8 in the Neon Rose series.
Medium flat index stock poster is in good to very good (B to B/B+) condition; there are a series of thin flattened bends/stress creases running vertically from just to the left of the top center edge (over the "is" of "Otis") down the length of the image to the bottom left/center margin (just above "Ubec"), plus a pair of very thin vertical bends in the lower left/right margin, a tiny corner bump or two and a whisper of handling, otherwise fine.
The conditional issues are VERY well-camouflaged on this example, it looks pretty close to mint unless you look at it really closely. A beautiful extra-vibrant image from the Neon Rose series.
