Design (uncredited) by Bob Masse, medium-thick flat index stock poster is in good (B) condition; a 2" tear in the top margin, pin/staple holes in each of the four corners with small nips out of the upper/lower right corners, light handling, several scattered tiny edge tears and nicks in the left margin and a few scattered tiny surface smudges, otherwise fine.
REALLY bright and unusual original 1st printing '68 Janis/Big Brother poster with a very strange design.
