Original 1st printing 17&1/2 x 12&1/4" "stock certificate" concert poster for Big Brother & the Holding Company (post-Janis Joplin/Nick Gravenites lineup), appearing with Sunflower, Spencer Hill and "other groups" at Andrews Amphitheater in Honolulu, HI on 7/18/1970.
 
 Artist unknown, medium-thin flat textured index stock poster is in very good (B/B+) condition; there is a soft brown stain/discoloration that goes just above "July" to the bottom edge, a series of VERY soft vertical roll bends going across the image (mostly visible from the reverse), a few handling dings here and there and a couple of tiny corner bumps, otherwise fine.
 
 Oddball Hawaiian Big Brother concert poster from the 1st post-Janis Joplin lineup of the band. Not one you see every day!
