Full of Yokoyama Kou's sketches, this is one book that Maschinen Krieger fans don't want to pass up. A few of the illustrations are coloured, but for the most part the designs really are just pencil sketches -- of people, mecha, engines, just about anything this artistic genius can come up with! There's a lot of commentary accompanying the text, all in Japanese; but that won't impede your enjoyment of the art. 208 pages, soft cover.
