A very interesting book both in its presentation as a "book-box" by the inserted reproductions and quality of writing. Reading is easy and for still unclear phases, several opinions of historians are addressed. In short: quality work, neat, pleasant and well documented. A double warning though: 1) From 12-14 years, not before (for young children, choose a simpler book to go and less fragile); 2) For fans already well documented, choose a less general work.
