Something about this image is jogging my memory. I've never read this particular book, yet I'm certain I've read something that describes this illustration perfectly! Excuse me while I sift through some musty boxes of tomes in the basement. Yes, here it is! Right on page 315 of the 1968 edition of the Official Handbook of the Boy Scouts of America:
When road-tripping in a hippie van, your troop may come across an old camp in the woods, the cabins of which may show signs of recent meteorite damage. Occupying such a place, you may encounter the likes of old Stella Blueshoes and her crazy hunchbacked son, ruthless members of a mostly female North Woods crime syndicate called the Sharkes. Your only defense is to have a statue of Anubis propped on the front seat of the van.
I was curious about this strange warning, particularly the odd instruction concerning Anubis, an Egyptian God of the Dead. None of this can be found in any other scouting handbook, both in previous and subsequent years. On further inspection, I found a name in the editorial masthead in the 1968 edition which sheds some light, albeit from a lava lamp, on this mystery.
