Labrador Outdoor : Sportsman's Hands-Free Lantern by Brion O'Connor Mini Book

Here's a practical kit designed to appeal to outdoors people of all ages. It includes a book of wilderness wisdom, accompanied by a lightweight, battery-operated gooseneck lamp, which can be configured for many uses. It fits at the front or side of a cap while fishing or hiking, and can be clipped to a book or a tent pole to provide light as darkness falls.

I found these in a mystery book box!
