This series includes one creative book for children aged 3+. There are 20 different shapes in the book. Thanks to a clever page-turning design, the book transforms the transportation shown on the first pages from a small vehicle to a very large one in a quick move. A small yacht turns into a large luxury cruise ship in a fold-out and a tractor at the farm turns into a huge repair truck. The folding page concept can fully satisfy all children’s curiosity and arouse their interest for knowledge and observation of things in detail.
