I hunted used bookstores and scoured the web for this book about four years ago. It turned out that this book was out of print. I finally managed to find it in a used bookstore in a suburb of Chicago and happily bought is for approx $25. Just recently I recently found out that this book has been re-issued in paperback form, and can be found in most major booksellers. According to the author’s website: “The new edition contains about 98% of the 1992 edition, plus about 25% new material: many new ambigrams, several new essays, plus a 16 page color insert featuring a number of my word-illusion paintings. It also features a new Foreword by Dan Brown, a complete and thorough history of my ambigrams, a section showing my favorite commissioned ambigrams, and a “How Ambigrams Are Created” section.”

Yes, Dan Brown, the author of The Da Vinci Code. Where we follow the adventures of Robert Langdon (coincidence?). He also wrote Angels & Demons. In fact, it was in Angels & Demons that I (like most people) first came across the work of John Langdon. I have been a fan of his ever since.

I also recently realized that Mr. Langdon is a fellow teacher at The College of Media Arts and Design at Drexel University. I have not had the pleasure of meeting him yet. But hope that opportunity presents itself in the near future!
