This hardcover concertina book folds out to a 108 in panorama depicting the vast swamps that covered the Earth 358 million years ago. Not just an art book, the book also explains the major events of the period in simple language. Printed on heavy card stock, the concertina, can be removed from its hardcover casing to be displayed. Each book in the Paleozoic series (5 books total) can be joined to create a 42 feet long image showing the evolution of life on earth. Each cover is debossed with a fossil of animal from the period.
