The original/first print poster was printed on vellum paper stock, and measures approx.  14" x 20".  A union logo printing credit (#72) appears in the lower right corner, and "Wes Wilson '66" appears along the lower right margin.

There are two distinct reprints (both authorized, measuring approx.  14" x 19 3/4"), the characteristics of which are as follows:

Type A  The bottom strip and image design are yellow.  The aforementioned union logo and Wilson credits do not appear.

Type B  The bottom strip and image design are chartreuse.  "Wes Wilson 16" appears in the bottom left margin.

Both of these posters were most probably printed in 1967

The original handbill was printed prior to the shows on very thin paper, and measures approx.  5 1/2" x 8 1/2".

There are three variations of the postcard as follows:

Type A  Same colors as the Type A second print poster
Type B  Same colors as the Type B second print poster
Type C  Same colors as the Type B second print poster, and the left & right borders have been trimmed off.
