Rare test issue, with art by Basil Wolverton. Of the 18 posters originally intended for the set, it is believed that only 12 were published, as there are no copies of 2, 9, 10, 13, 14, or 18 known to the hobby. This poster has a tiny piece missing from the center left border, multiple small tears along the edges, red marker near the bottom edge, and an additional crease above the center factory fold
