This book was originally published in 1984. The one I have is the 17th reprint from 2002. Pretty amazing.
In typical Studio Ghibli art book style, this paperback art book also sports a canvas dust jacket. It's 192 pages in all with character designs, background paintings and film stills. Most of the art are watercolour painted. Hayao Miyazaki drew many of the storyboard sketches with his usual loose watercolour rendition that you still see in other art books.
At the back is a look at how some of the anime scenes are created, like how they animated the catepillar-like creature among others. It's all in Japanese though.
It's a nice addition to the Studio Ghibli "Art of" series, featuring some good old school fantasy art.
If you like this book, you'll want to check out Nausicaa of the Valley of the Wind: Watercolor Impressions also.
