As the title states, this is a compilation of Phoenix Wright art. The illustrations in this book are not only the in game poses and facial expressions, but also full body illustrations and the occasional character in a different outfit sort of thing (i.e. Maya wearing a school girl uniform, Mia in a chinese dress, etc). You will find the artwork of the case title screens as well as some fun not-in-game art.
When compared to other video game related art books out there, this book has a lot more illustrations and variety. I have my fair share of art books and this one far surpasses those; Udon really nailed it with this book and their other artbooks such as Mega Man Complete Works and The Art of Street Fighter.
The cover has a nice texture and the binding is sturdy. The pages themselves are a nice thick quality. Overall, the physical quality of the book is really outstanding.
I believe the only thing that would have made this book better is to have all the extra artwork from the game, such as the group shot at the end of the first game, in-game crime scene illustrations, etc. A lot of the in-game screens did not seem to make it into this book, but again it is still outstanding overall.
I highly recommend it!
