Can You Pass the Acid Test? Throwback Uncle Sam T-Shirt

Join the legacy. Celebrate the Acid Tests. And ask yourself: Can YOU pass?

Step back into the heart of the psychedelic revolution with this “Can You Pass the Acid Test?” T-Shirt, a faithful tribute to an iconic piece of countercultural history. Inspired by the original Merry Pranksters membership card of 1965, printed by Ken Kesey’s Intrepid Trips, Inc. and distributed at the earliest Acid Tests, this shirt revives the image that became a badge of identity for an entire generation of seekers, dreamers, and Deadheads.

The design features a bold parody of the classic Uncle Sam recruitment poster, pointing directly at you with the immortal question: “Can YOU Pass the Acid Test?” Just as the original cards were handed out at those legendary parties in San Jose and San Francisco, where the Grateful Dead first took the stage and the Pranksters blurred the lines between art, music, and communal experiment, this shirt invites you to carry that same spirit of curiosity, rebellion, and play wherever you go.

The soft heather fabric and easy unisex retail fit make it an everyday go-to, while side-seamed construction and shoulder taping help it keep its shape wear after wear. Whether you’re wearing it to a show, hanging out with friends, or simply channeling your inner prankster, it’s more than a piece of clothing, it’s a conversation starter, a symbol, and a wink at the movement that forever changed music and culture.
