The 1st printing (see FD016) was deliberately printed slightly out of register to suggest the visual effects of LSD. This pre-concert edition is 14 3/16" x 19 7/8" and shows "The Bindweed Press, San Francisco" at the bottom left hand corner of the poster. 1,000 posters were printed for this run.
The 2nd printing is 14 1/4" x 20 1/2" and omits the Bindweed credit. "No.16-2" is in the bottom right corner and "(c) Family Dog Productions 1725 Washington Street San Francisco" is in the lower left corner. The 2nd printing was printed after the concert, without the distortion of the original printing.
