The 1st printing poster has a chartreuse image and measures 14" x 20". This poster bears union logo 72 in the lower right corner and "Wes Wilson '66" runs vertically up the lower right margin. 1,500 original posters were printed before the concert.
The post-concert 2nd printing of the poster (see BG016-2) has no union logo and no Wes Wilson credit. The image is yellow, and it measures 13 15/16" x 19 3/4".
The 3rd printing also lacks the union logo, but "Wess (sic) Wilson 16" appears at the bottom of the left margin. The bottom strip and design are chartreuse, and this post-concert printing measures 13 15/16" x 19 3/4".
