The 1st printing of this poster bears "Code No. 41 (1)" right above the ticket outlet information in the bottom left hand corner. The original was printed on either coarse, random pattered stock or smooth, plated, grid patterned stock. Some 1st printings exist that still have an untrimmed white border that measures about 3/8". The original generally measures 13 1/8" x 19 1/16" and was printed before the concert.
The post-concert 2nd printing has "Code No. 41 (2)" above the ticket outlet information in the bottom left hand corner and measures 14" x 20".
