I am currently reading The Wild Robot, it is a hardcover (since I was just dying to read this and the paperback isn’t out yet). So I started reading it today, and decided to flip the jacket off to see if there was something under there. Low and behold, there was a robot underneath the jacket. Standing proudly on the bright white background. What you probably can’t see on the pictures is that the robot isn’t just a drawing, no, the image is set a bit deeper and you can trace the robot with your fingers.
