Original 1st printing 13&7/8 x 20" concert poster for the Doors appearing at the Matrix in San Francisco, CA from 3/7-11/1967.
Art by Victor Moscoso, image is # 10 in the Neon Rose series and is featured in the Art of Rock book on page 169 (plate 2.127, the book depicts the orange-border 2nd printing, this green border version is the 1st).
Medium flat index stock poster is in very good to excellent (B/B+ to B+) condition; there are a series of ultra-soft/nearly-invisible horizontal roll bends, a soft 5" diagonal bend in the top left margin area, a set of tape pulls on the reverse, a 1/4" tear in the top right margin, a hint of surface wear and a touch of handling, otherwise fine. Very bright colors on this example, no major issues overall.
