This is the classic story- illustrated so that children may fully appriciate its humor.
This was the first (of well over 1000) read-alouds I have done, I read it for a second-grade class that I was familiar with, but when I got toward the end, with the picture of the emporer from behind, totally naked, the class wouldn't stop giggling (my impression was that it was mostly the boys), and I had to stop. Now I see why they have a penguin or a dinosaur in the title role most of the time.
