This is a Japanese-language illustration (art) book.
This visual mook --the first 3D visual mook for Code Geass--contains 122 full-color pages featuring the figures and models available for this animated series. There are also 16 black-and-white pages of mecha designs. The comprehensive introduction to the subject matter already makes the book well worth getting, but the photos of the scratch-built figures in the opening pages are sheer delight. And they've thrown in a double-sided full-color fold-out poster as well! Softcover with dust jacket. All text is in Japanese.
