This postage stamp collage incorporates a piece of deep green paper on the lower portion of the composition.  The symmetrical design of the five different sized triangles also in shades of green, reflect each other above and below.  The title refers to the idea that “safe passage” may require going underground or biding one's time before it is safe to emerge and move forward.  The imagery on the stamps depict space travel, maps, arrows, chemistry, and travel with plenty of numbers thrown in.
