The pre-concert 1st printing is on vellum and bears union logo # 72 on the bottom right corner. This printing measures 14" x 20".
The 2nd printing, also on vellum, was printed after the concert and bears a "4(2)", which is not the poster's correct identifying number, in the lower left corner, and a "Lorin Gillette" credit across the bottom margin. This image measures 14" x 20", and the green-colored ink varies from light to olive to dark.
The post-concert 3rd printing is 14 1/8" x 20 1/2" on uncoated index and displays no union logo or Gillette credit. "No.9-3" appears in the lower right corner and the Washington Street address is in the lower left corner.
