Ok, this being my first guitar book, to air ok. Even if all the posts on humor US mistranslated his true ... never mind. However, I expected to receive the book of illustration, not !!! I received the new formula (discount) over hardcover, convenient as it was open when we read it and played at the same time! but a flexible plastic cover, the book is closed all the time = painful. Same for the supplied CD door, anicenne editing allowed to carry it in integrated plastic bag, the new formula = paper bag, when it is open = farewell transport CD with the book.
