Original 1st printing (index stock version) 14 x 20" concert poster for Big Brother & the Holding Company (featuring Janis Joplin) at the Matrix in San Francisco, CA on 1/17-22/1967. Art by Victor Moscoso with a photo by Lisa Bachelis (Law), image is # 3 in the Neon Rose series and is featured in the Art of Rock book on page 168 (plate 2.126). Medium flat index stock poster (OP-2 in Eric King's book) is in absolutely gorgeous near mint (A- to A-/B+) condition; just a trace amount of surface/handling wear (a couple of ultra-soft pinch dings and one or two tiny surface scuffs), otherwise fine. An overall VERY crisp example of this early Moscoso/Neon Rose poster.
