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", and the background of the box is navy blue. "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. The background in the box is purple and "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 also displays a purple background in the box, but this reprint 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".
