Mailing a Metaphor

From this set of panels the mailing opens one last time, its insides revealing that it is in fact a 24-inch-by-27-inch poster of a forest on one side. Resting inside the maze of panels and now revealed are the mailing’s other elements: a 3.5-inch-by-8.5-inch membership acceptance form; a 5.5-inch-by-8.5-inch insert that lists the member benefits, which include a tote bag premium; and a BRE.
