The pre-concert 1st printing of this poster is on matte uncoated stock that matches the postcard. It is a lighter brown/gray than the reprint, and it measures 14 1/4" x 20".
The 2nd printing is characterized by its darker colors, especially the brown. It is also more narrow, measuring 14" x 19 7/8". There is a tiny "cut" mark in the middle of the bottom margin right below the ticket outlet information that is not present on the 1st printing. It was printed on smooth stock after the concert.
