Original 1st printing 11&3/8 x 17&1/2" advertising/promotional poster for the 6/15/1967 issue of "Avatar", an Olympia, WA-based underground newspaper.
Artist unknown/not credited, medium-thin flat vellum stock poster is in used (B-) condition; there is a large 3&1/2" diagonal tear in the top center margin, a small wedge of missing paper, a small tear and creasing in the lower right corner, a fair amount of edge wear (numerous small tears), tack holes, a few stray surface scuffs and pin-prick pulls/stains, light toning, tape pulls on the reverse... you get the idea.
Conditional issues aside, still a pretty unusual Pacific Northwest psychedelic item from a very obscure regional underground paper. You can read more about the paper (and this issue- #2) HERE;
