I am an avid fan of Dragon information and this book provided quite a lot of that. The book makes bold claims as to the validity of the existence of such creatures but never once produces any proof of their existence. They claim to have pictures but never show any save the ones where the Dragons are 'hidden'(or mimed as this is the term they use). The only year mentioned in the whole book is the published date(1980, not 81 as in the description). No addresses are published and only references to 3 pages of Bibliographical cited material. All in all, I was unimpressed with a book that was trying to convince me that Dragons do exists. I am currently trying to follow up on their claims, checking references and such.
