The 1st printing variations are based primarily on the stock used, so it may be necessary to compare the different printings side by side. Both 1st printings were produced prior to the concert.
The 1st printing A is on smooth plated white index that measures 13 3/4" x 22 1/2". The stock used is .0085" thick.
1st printing B mirrors the A version except it is on coarse, porous stock that also is .0085" thick. It measures 13 11/16" x 22 1/2".
In 1986, Wes Wilson authorized a 3rd printing of the poster and added red, blue and orange colors to this reprint. It measures 13 1/2" x 21 15/16".
