Original 1st printing 13&7/8 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; just a tiny cluster of staple holes in the top center margin, a couple of nearly-invisible soft diagonal bends in the upper right corner and a whisper of handling wear, otherwise it is a SUPERB example of this oddball early-'67 Bob Fried poster from a cool little Saturday-afternoon program for hippie parents and their kids.
