An extraordinarily rare Merry Prankster’s ID Card from the legendary Acid Tests. This was printed by Ken Kesey’s Intrepid Trips, Inc. in late 1965. The membership card is thought to have originated around the time of the second Acid Test, held at Big Nig’s house in San Jose, California, on December 4th, 1965, an occasion notable for the Grateful Dead’s first Acid Test performance.

One side pictures a pointing Uncle Sam and reads CAN YOU PASS THE ACID TEST?, parodying the classic “I Want You for the US Army” recruiting poster.

The other side, designed to be filled out by the bearer, has spaces for name, address, birthplace, etc and photo and signature, declaring “I am a member of Intrepid Trips, Inc. and am doing nothing”. This is the only example of this very rare card we’ve had. 3 1/2″ x 2 1/8″, in near mint condition with a faint bit of toning to the left edge. With Recordmecca’s written lifetime guarantee of authenticity.
