 Medium flat vellum stock poster is in excellent (B+) condition; there is a 2&1/2 x 3&1/4" square of light toning in the lower left corner, along with a few stray thin bends/light creases scattered around the outer margin area, a tiny pin-prick spot in the top left corner and a few soft handling dings here and there, otherwise it is a GREAT-looking example of this uncommon Pacfic Northwest festival artifact with a great design and a killer lineup.
