The 1st printing of the poster is characterized by a slightly darker blue "band" that runs horizontally right below the bottom pink border. There is a little blue dot just to the left of "Moscoso". "61-1" appears in the bottom left hand corner. This original poster was printed before the concert and measures 14" x 20".The 2nd printing of the poster omits the blue band described in the 1st printing and retains the dot to the left of Moscoso. "61-1" appears in the bottom left hand corner. This post-concert reprint is on fluorescent white stock, and it measures 14" x 20".The post-concert 3rd printing omits the dot to the left of Moscoso. It replaces the full dash in the "61-1" in the bottom left hand side of the poster with a dot in between the numbers. It also measures 14" x 20".
