This original 1967 poster by the legendary Stanley Mouse announces one of the foundational events of the American counterculture: A Gathering of the Tribe for a Human Be-In. Held on January 14, 1967, in San Francisco’s Golden Gate Park Polo Fields, this peaceful gathering brought together thousands of artists, activists, poets, musicians, and free spirits in a unifying celebration of community, consciousness, and resistance.
Designed at the height of the psychedelic movement, Mouse’s poster distills the spirit of the era into visual form. Heavily influenced by Art Nouveau and deeply rooted in the visual language of the West Coast underground, the piece reflects a world where art and revolution merged. As a key figure of the San Francisco poster scene, Mouse helped define the aesthetics of the 1960s with his ornate, fluid lettering and vivid dreamlike compositions.
The Human Be-In was more than just a concert or demonstration—it was a prelude to the Summer of Love, the moment that would make the Haight-Ashbury district a global symbol of youth-led cultural transformation. It was here that the word “psychedelic” first crossed into suburbia, carried by the voices of icons like Allen Ginsberg and Timothy Leary, and the imagery of artists like Mouse.
Today, this poster remains a highly sought-after piece of psychedelic ephemera, not only for its aesthetic power but for its direct link to one of the most emblematic moments of 20th-century countercultural history.
