This is a classic sixties psychedelic image, featuring a Yin Yang symbol in the middle which is formed by the lettering.

This poster was printed just once, prior to the shows.  However, there are several subtle color variations (and one minor size variation) within the run.  Original postcards exist that match each color variation of the poster.  These posters measure approx.  14" X 20"

The original postcard, printed prior to the shows, measures approx.  5" X 7", and exists with two different backs (place stamp here & bulk rate).
