i know if a great book called drawing on the right side of the brain. it teaches on the principle that art is a learned thing and only sometimes innately understood but a person, but it can be taught to anyone.

there are new ones from 11.51 and used from 9.00 something.
a personal note on the book. this was recommended by my high school art teacher. he was the best art teacher i ever had. i got the book after i graduated HS, and the book still helped me further my skills. The book is
meant for people with no art skills yet, and it helps teach you how to look at things properly in order to draw them.
EDIT: this is not a manga book or a book on 'step-by-step instructions on drawing specific objects.
