Sorry,but unless Krpton understands French, he can't read the book, which means he's screwed.
Oh, yeah. There's also this book called
Le Grand Livre de Dragon Ball (The great Dragon Ball book in english). This book is like an illustrated Dragon Ball bible. It has almost EVERY color picture (265 illustrations to be exact) Akira Toriyama ever drew concerning Dragon Ball. The drawings are shown chronologically (from when Goku was a kid to his SSJ 3 days), so you can very well see the evolution of Toriyama's style throughout Dragon Ball. The book also includes a comment on each drawing and an interview with Akira Toriyama.
Cover of the book:
Useless to say I've got both of these books. Ten of these books were released in Japan, but only two were realeased in French. I'm pretty sure the remaining 8 will be relaeased as well.
