I have a few early thin paper handills to list from 1966-67. This is an original handbill/ ticket order form for the Monterey Pop Festival June 16-18,1967.
Acts included the Grateful Dead, Jimi Hendrix, Janis Joplin & Big Bros. Size is 4" x 9" folded 12" x 9" opened, in excellent condition (minor crease, somebody wrote a tiny "1967" on back).
