Original 1st printing 15&1/4 x 20&1/4" concert poster for the Wildflower appearing at the Matrix in San Francisco, CA.from 8/23-28/1966.

 Art by Jon Adams, medium-thin flat index stock poster is in very good to excellent (B/B+ to B+) condition; there is a soft 3 x 1" stain along the lower left margin, plus a few minor edge/corner tip bends, a tiny nip out of the bottom right corner tip, a 3" thin vertical stress bend in the upper left margin, a few soft handling dings here and there and a couple of tiny nip tears/dings along the top margin, otherwise fine.

Nice-looking mid-1966 oversized Matrix poster with a charming design.
