“Expedition Edition” features a hi-visibility “Antarctic Survey Orange” front cover and a “Polar Night Black” back cover, with a subtle varnish effect featuring a topographic map of Antarctica. The body pages feature our popular Dot-Graph graph paper, printed in light gray. The whole book is printed on Yupo Synthetic paper, an amazing water- and tearproof paper extruded from polypropylene pellets in Chesapeake, Virginia.
