Original 1st printing 14 x 20" concert poster for Big Brother & the Holding Company (featuring Janis Joplin) appearing at the Matrix in San Francisco, CA from 1/31-2/5/1967.

 Art by Victor Moscoso, image is # 4 in the Neon Rose series.

 Medium flat index stock poster (OP-1 in Eric King's book) is in absolutely GORGEOUS mint/near mint to near mint (A/A- to A-) condition; just the tiniest whisper of handling/edge wear (a stray pinch ding or two and a couple of ULTRA-tiny bends in the corner tips) and a nearly-invisible fingerprint smudge in the right center margin, otherwise this is a SUPER-crisp example of one of Moscoso's most eyeball-searing Neon Rose images.
