The Idaho Fishing & Hunting Guide was already mentioned upthread, but here's a pic of my copy that includes an interior shot of Harmon and his hunting partner Linda Moulton.

Moulton was the reigning Miss Idaho at the time, and she went on to become a pretty well-known ufologist, conspiracy theorist and cattle mutilation "expert". She's appeared in a number of History Channel and Discovery Channel UFO shows and written books on alien abductions and crop circles.
