Original 1st printing 13&7/8 x 20&1/4" cardboard event poster for the 6/24-25/1967 Synanon Street Scene, a rehabilitation center-sponsored event held in San Francisco, CA.
Design by "BK", thick cardboard stock poster is in used (B-) condition; a series of hard horizontal bends/creases traversing the poster in several areas, with the crease in the center exhibiting a rather large horizontal split, plus there is a fair amount of toning, surface wear, a decent-sized moisture stain running along the left margin, a few stray surface scuffs and dings, etc... this example was VERY hastily pulled down from public display around the time of the event, and taken to ANOTHER event, where the story gets interesting....
The poster was carried by the original owner to the Magic Mountain Festival on Mount Tamalpais on 6/11/1967 (dated at the bottom), where he (or she) had the poster autographed (in a variety of pens) by Jefferson Airplane members Paul Kantner ("Love Paul, Stop War"), Grace Slick, Jack Casady and Marty Balin, plus David Crosby from (at the time) the Byrds, Sky Saxon and Rick Andridge from the Seeds and Bay-Area folk rock duo Blackburn and Snow (see close-ups)... fortunately, this person also had the foresight to photograph (on an old Kodak Instamatic camera) some of the musicians (which will be included with this lot), including Sky Saxon (signing the poster), Jack Casady (being handed a pen) and Blackburn and Snow (backstage). WOW!!!
The period autographs WITH PHOTOGRAPHIC PROOF kinda wipe out the conditional issues on this one... a MEGA COOL ORIGINAL 1967 psychedelic rock artifact with an INCREDIBLE set of signatures.
