Ultra-rare U.S. premiere engagement (at NYC's Elgin Cinema) poster for underground satire directed by the artist Wynn (spelled "Win" on the poster) Chamberlain. A once in a lifetime cast - including Abbie Hoffman, Sam Shepard, Sally Kirkland and the Warhol superstars Ultra Violet, Candy Darling and Taylor Mead - yet the film was more or less unavailable and unscreened for nearly 40 years, until Chamberlain got a print and screened it in NYC in 2011. The poster artwork is by Gilbert Shelton.
