Can You Pass the Acid Test? Throwback Poster T-Shirt

Celebrate one of the most iconic moments of the psychedelic era with this Can You Pass the Acid Test? throwback tee, featuring original artwork by Paul Foster, a core member of Ken Kesey’s Merry Pranksters.

First appearing on handbills and posters promoting the legendary Acid Tests of the mid-1960s - where the Grateful Dead provided the soundtrack to a whirlwind of strobe lights, films, and free-form chaos - Foster’s art remains a defining image of the counterculture. Now it’s reimagined as a wearable piece of history.

This unisex tee is printed in bold detail on the Bella+Canvas 3413 Tri-blend, a lightweight and breathable shirt available in Athletic Grey, Mustard, Tan, and White Fleck colorways. The super-soft fabric is made from 50% polyester, 25% combed ring-spun cotton, and 25% rayon.
