Original 1st printing 13&1/4 x 20" event poster for "Popcorn Happening", a children's program featuring films, clowns and other assorted diversions, held at the Fillmore Auditorium on 4/22/1967 and at the Matrix on 4/29/1967 (both venues in San Francisco, CA).
Art by Bob Fried ("Singing Mothers LSD Relief Society"), image is not a numbered Bill Graham/Fillmore image (this show falls on the same date as the BG 60 show).
Medium-thick vellum stock poster is in excellent (B+) condition; aside from a tiny bend in the lower left corner, a pair of stains in the right margin, a small bump and a thin vertical bend in the bottom right corner tip and a few soft handling dings scattered around the image area/margins, this example is pretty sharp-looking.
REALLY neat oddball Fillmore poster from a cool little Saturday-afternoon program for hippie parents and their kids. VERY early Bob Fried piece!
