Ed Emberley's drawings books are amazing. I have never seen another book allow children to do what this book can. Even fairly young children can manage many of these faces (though the fine lines are far easier for, say, 6-year-olds than 4-year-olds). And, of course, they are fun for adults as well. I'm not much of an artist (as much as I wish I were), but I feel like I can actually do something even slightly artistic when I follow this book, and that's a good feeling.
