Just wondering if anyone can tell me if there's a difference between

"The Art of Nausicaa of the Valley of the Wind: Watercolor Impressions"

[color="Sienna"]http://www.amazon.com/Nausica%C3%A4-Valley-Wind-Watercolor-Impressions/dp/1421514990/ref=pd_bbs_1?ie=UTF8&s=books&qid=1217746523&sr=8-1[/color]

and the earlier book "The Art of Nausicaa"?

I assumed they were one and the same but now I'm not so sure.
If they're quite different I will buy both.

Can anyone help?

Thanks
