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 absolutely fantastic near mint (A- to A-/B+) condition; aside from a slightly off-register pass of blue ink (most prominent towards the top of the poster) and maybe a negligible handling ding or two, this one is just about as crisp/sharp as they come... a GORGEOUS example. Check out an over-the-top version of Them's "Gloria", recorded at the club HERE:
