It was published in 1994. I have searched high n low and have not seen another book like mine. A good friend of my fathers who died a few years ago was an avid fly fishing guide and took people all around the USA & Canada on junkets to fly fish. I think he gave this very special book to my dad after one of his trips to Canada. Based on my Google searching I think my book is a first edition since the only thing out there is the Red Book.
