Thin flat stock handbill is in very good (B/B+) condition; a large tack hole with a slight indentation in the top center margin, a set of tiny staple holes in each of the four corners, a few stray light handling dings/tiny creases scattered around the image area/borders and a few ultra-minor surface spots, otherwise fine.
ULTRA uncommon early (1966) Fillmore benefit handbill.
