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 VERY sharp near mint (A-) condition; just a small round indentation in the top center margin (above the "e" of "Recording"), a couple of tiny stray edge dings and a well-camouflaged pinch ding or two hiding within the image area and that's IT.... no other issues to speak of.

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