Original 1st printing 14 x 20" concert poster for NYC-based blues/folk/rock band the Blues Project appearing at the Matrix in San Francisco, CA from 9/7-15/1966.

 Art by Jon Adams, image is featured in the Art of Rock on page 167 (plate 2.122).

 Medium-thick vellum stock poster is in good to very good (B/B+) condition; just a touch of handling wear (mostly along the right margin), a tiny spot in the top right border, a light amount of surface wear and a large green magic marker scrawl across the reverse top margin ("YARDBIRDS 33", just a shadow of bleed-through), otherwise fine.

 Great-looking original late-'66 Matrix poster with a pretty cool design.
