Grateful Dead – Ken Kesey – The Acid Test 1966 Promotional Poster

A very rare promotional poster for the 1966 album "The Acid Test." Bay Area recording studio Sound City recorded as their first session an in-studio Acid Test with Ken Kesey, the Grateful Dead, and members of the Merry Pranksters and issued it on their small local label. It sold very poorly, and original copies can now fetch as much as $1000. This is a 1966 promo poster for the album, utilizing the cover artwork but measuring 14" square. We know of only two other examples that have surfaced in the 45 years since this album was released. This example has had some minor restoration by an expert paper conservator, to fix some small edge tears and pinholes and deacidify the paper, and it now is in near mint condition. A great image from a golden era.
