The flyer exhibits super fresh white paper, razor sharp corners and is free from all nicks, cuts, tears or pinholes! This was the last psychedelic Acid Test event before LSD was made illegal in California (in October 1966). Nicknamed Whatever It Is or The X Handbill, represents oodles of history both the Grateful Dead and head Merry Prankster Ken Kesey were there. Not Bill Graham (BG) or Family Dog (FD) but coincides with the start of both of the respective poster series. & be sure to check my other items.The item "Original 1966 Acid Test Handbill Poster SF State Grateful Dead MINT" is in sale since Thursday, January 28, 2021.
