This was the only letterbox in existence for 40 years, and in that time the box evolved from calling cards to postcards and finally to a rubber stamp and logbook like you will find today. Letterboxing has a long history, starting in 1854 at Cranmere Pool in Dartmoor, England by a James Perrott who left his own calling cards in a box in the woods so visitors could contact him and leave their own after completing the difficult hike. Sizes of letterboxes range from tiny tins to larger tupperwares and even watertight bags.

There are letterbox-geocache hybrids, where a geocache includes a stamp for a letterboxer as well as goods to exchange for the geocacher. Geocaching is about exchanging goods with strangers rather than collecting stamps (like with letterboxing) and geocaches must be found with GPS coordinates rather than clues. Letterboxes are not to be confused with geocaches, which are also hidden boxes in public places. There are over 90,000 letterboxes in North America alone and hundreds in Colorado, mostly hidden outdoors in weatherproof containers, often under rocks or logs. Letterboxing is an international treasure-hunt style outdoor activity where the goal is to collect stamps in a personal logbook and leave your own stamp-signature at each letterbox you uncover. Have you ever wanted to be a part of a secret society? Do you like riddles and puzzles and discovering something special that hides in plain sight? If so then you will definitely find amusement in the little-spoken about hobby called Letterboxing.
