I first came across a Sara Fanelli book at the library in which I work and was immediately captivated. Her artwork--a combination of collage, drawing & painting--has the color and spontaneity of children's art, but the choice and handling of materials is very much that of a "mature" artist.
The Doggy Book has the added bonus of fold-outs in the front and back which transform the book into a doggy (Bubu?). Complete with tied-on "bone" bookmark--great fun!
I'm a fan of children's picture books anyway--some of the best examples of contemporary art are to be found inside them, and Sara Fanelli is one of the best and most original!
Check out her other titles, too.
