It is the Firefly Visual Dictionary. I bought this at Restoration Hardware YEARS ago... it looks like Barnes and Noble only has used copies. Although a used copy wouldn't be such a bad investment seeing as our book is practically torn to shreds it is used so much.
This book contains visual diagrams and descriptions for everything from a human body, to the solar system, to how an airport is laid out to the parts and workings of musical instruments. It is a great learning tool for exploring children and parents!
