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 good (B/B+) condition; there is an approximately 10" long thin horizontal stress bend traversing the image area between "Matrix" and "Sept 7-15", along with a light stain along the bottom right margin, a couple of tiny nip tears and crinkle creases along the lower right margin, a few stray stress bends scattered along the upper right margin, a few soft pin-prick age spots scattered around the outer margin area, a few soft handling creases here and there and a couple of soft smudges on the reverse side, otherwise fine.

 Great-looking original late-'66 Matrix poster from the AOR.
