I just sent this link to my my brother.
Although we don't use coloring pages in school, I can see how one might prefer this kind of coloring book to the Disney kind that is exclusively pictures of princesses in poofy dresses. Let's make room for some new subject matter!
Plus, the Yellow Bird Project is about T-shirts designed by indie rock artists, with all profits going to their chosen charity. Another good reason for a new coloring book!
