Need to build a bomb shelter?

Arnica has uncovered this rare document from the bowels of the archives of the filing cabinets of the manila folders of the top secret laboratory Arnica calls home.

This is an actual publication.

Arnica has an afriendance (someone who is more than an acquaintance but not so close that Arnica could come knocking at 2AM asking for a bowl of sugar) who grew up in a house that had a bomb shelter in the back yard. He used it as a play house and now uses it as a dark room.

Anyway, enjoy this and share it with nobody. We don't want this getting out into the mass population. It could start a run on dark rooms.
