Discover the wonders of the human body in this ingenious and fascinating book. The first part is packed with fun facts and clear, appealing illustrations.

Study them separately, or turn back the pages to build up a complete human body. It's guaranteed to keep young readers occupied for hours on end. Perfect for children aged 6 and up.
