The 1st printing is 14 1/8" x 20" on vellum and shows "The Bindweed Press San Francisco" in the lower right corner. There was a late change in the billing that is reflected on some copies of the 1st printing; the words "FRI. AND SAT. NIGHTS ONLY" have been altered with the addition of a sticker over the word "SAT." The word "SUN" is hand-written on the sticker. Some of the 1st printing posters have this sticker. This original poster was printed prior to the concert.
The post-concert printings were done on different paper stocks and both bear the "No.15-2" notation in the lower left corner. Both versions show the Washington Street address in the lower right corner and omit the Bindweed Press credit.
2nd printing A is on a thin 5.5 point paper stock and measures 14 3/16" x 20 1/2". The colors are more muted, and the figure shows less detail.
2nd printing B is on a thick, 8 to 8.5 point glossy paper stock and measures 14 1/4" x 20 1/2". The colors are more intense and the figure more detailed.
