I picked this book up last spring or the spring before at the Smithsonian in Washington when we were going through with Collin and Parker. It is a beautiful little slipcased book, and had the best illustrations I've ever seen of dinosaurs.
Only as I started working my way through it did I realize that it was about the dinosaur collections of the Muséum National d’Histoire Naturelle in Paris, and was created to coincide with a traveling exhibition of that museum's T. Rex "Trix" and the international release of Jurassic World. But it provided an extensive background on the history of the collections and of the history of paleontology as applied to dinosaurs, including a substantial collection of paintings and engravings from the earliest days of dinosaur illustration.
Overall, a very entertaining book.
