I'm looking for drawing books for a 6 year old girl.  It doesn't have to be children's books, but something that she would like to draw.  Examples: disney princess, tinkerbell, flowers, trees, ocean scenes, animals, etc.

Does anyone have any on the shelf or would recommend any in particular?  I'm not an artist, but our daughter loves to draw and I'd love to encourage her.

(If someone has several books and they would offer a deal that would be double the blessing)
