The basic idea is simple enough: Clues, usually posted on a website, lead to the secret location of a “letterbox.” And yet there is much more to know. The Letterboxer’s Companion is a complete introduction that covers everything from a history of letterboxing to tips on writing and following clues, from instruction in carving personal stamps to letterboxing etiquette—in short, everything an aspiring letterboxer needs to get started.
