[Artifact] "Into the Unknown" 1931

This module was bundled with the third and subsequent reprintings of the boxed set. The "girl in peril" artwork was considered too lurid, and was covered by a promotional sticker starting with the fourth reprinting. This intact copy is a rare find.  Merritt was the first pulp author to recognize module-writing as a profitable new fiction market, and we all know the other big names who soon jumped into the game.
