Go to Amazon, They have a show about Petter Amundsen about an hour and a half. Surely you can spare that much time before you get on forums putting a great man down, an intelligent man, a man that has did the world a service by his brilliance. I do not understand you naysayers. I know for a fact Petter Admundsen's work is legit and it follows every source of Sir Francis Bacon's Codes and other code makers of the early 1600's. If you can not say anything good about someone please do not say anything at all as it slanderous when you do not know what you are talking about.
