The original/first print poster measures approx.  14" X 20".  The border color of this poster is a medium pink, which matches the color of the original cards. In addition, in the lower right corner (just inside the image) the lowest row of
horizontal dots (a total of six) is completely orange, as are most all of the dots in the image.

The second print poster, an authorized reprint, measures approx.  14" X 20". The border color of this poster is a deep/intense pink (magenta...some are even red), which does not match the original cards.  On this poster, the bottom row of dots are darkened (one or two may be orange), as are most of the dots in the image. This poster bears the notation "No. 59-1", but it is NOT an original poster. This poster was printed no later than 1968,

The original postcard was printed prior to the shows, and measures approx.  5" X 7".  Both place stamp here & bulk rate back cards are known to exist.
