The Zig-Zag image was one of the first rock posters to be pirated and sold after the concert. Chet Helms was so annoyed by the trafficking that he had a "Genuine Counterfeit" stamp made, and he and Family Dog staffers stamped as many copies as they could find. The pre-concert 1st printing A is 14 1/4" x 19 15/16" on vellum and shows "The Bindweed Press San Francisco" in the lower left hand corner. All the lettering was done in metallic pewter. WE BELIEVE THROUGH OUR RESEARCH THAT THIS IS A FIRST. WE DO NOT GUARANTEE AS THE PEWTER COLORING IS FADED FROM YEARS OF DISPLAY FROM THE PRIOR OWNER. THE SIZE DOES MATCH UP. THIS IS ALSO NOT. SECOND OR A THIRD, BASED ON THE COLORS AND THE MARKINGS. THERE IS LIGHT CONDITION ISSUES WITH THIS POSTER BEING A SMALL TEAR IN THE BOTTOM RIGHT CORNER, AND PINHOLES AS WELL AS A DEALER STOCK STICKER ON THE BOTTOM. THE DEALER THAT OWNED THIS WAS A WELL KNOWN HEAD SHOP AND HAD MANY ORIGINALS AND FIRSTS - ALL OF WHICH WE SOLD - AND HE DID NOT OWN ANY REPRODUCTIONS AT ALL. WITH ALL THAT SAID - THIS IS PRICED ACCORDINGLY AND PLEASE NOTE - THJERE ARE NO RETURNS ON ANY OF OUR PRODUCTS. ASK YOUR QUESTIONS FIRST.
