Original 1st printing 12&3/4 x 18&1/4" concert poster for S.F. psych-folk band the Wildflower appearing at the Matrix in San Francisco, CA, from 10/28-30/1966.
Art by Tom Weller, image is featured in the Art of Rock book on page 167 (plate 2.125).
Medium-thick flat index stock poster is in good to very good (B to B/B+) condition; a set of tack holes (all four corners and in the "h" of "The", a series of thin handling bends and light stress creases scattered around the image area, a few stray surface smudges (most prominent around the show dates) a small bend in the top left corner and a set of tape pulls on the reverse, otherwise fine.
Overall, a very nice-looking example of this semi-scarce early (1966) 1st printing Matrix poster from the Art of Rock.
