This binded book is dated 1958 and is the first edition. It has been used and has stains on front and back of the soft cover. The side of binder has two tears. See picture. The pages have yellowed have wear. The glue holding the material has darkened and has stains many of the materials but you can still see and feel the bottom half of the material square. See picture for condition. Previous owner wrote his name on first page and I left some notes they made in the book. I still love this book and I am thinking of keeping it! So buy it before I change my mind! This is the earliest and only full original 1958 version I have found for sale.
