I recently bought the newly released anime guide for S1 of SB and I didn't find any posts about it in the comm. So this is aimed at those who are considering buying it. Sadly I don't have access to scanner here so all I can show you are camshots. (I apologize for the flash reflections and my hand showing in the pictures.)
Cover: The book has 130 pages and it's printed on glossy paper, so it's quite thick.
Poster (one sided):
Splash page:
Chara design sample 1: Masamune is the only character that gets a full spread to himself (and his horse)...
Chara design sample 2: ...the rest are grouped by their faction, 2-4 per spread.
Color spread sample: I counted 9 such spreads in the book.
Episode summaries: Each episode is summarized with a collage of pictures, there are also collages of the OP and ED animations.
Storyboard: 14 pages of sample storyboards from some key scenes.
Background art: 8 pages of designs for backgrounds and locations.
In the end is a short section which appears to be seiyuu talk and character Q&A. My kanji reading is abysmal so I haven't taken a very good look at it yet.
I like the book and I'm quite happy about my purchase. If you're pondering whether to order it, hope this helps you.
