The play mat that is always on the go: The Leporello cardboard picture book quickly transforms into a huge bustling scene full of houses, shops, playgrounds, and of course, streets. This way, the surface for the favorite toy cars is always ready to use and just as quickly put away. Small search tasks complement the bustling scene: Can you find the secret message in a bottle? And who is the police dog keeping such a close eye on? By adding the second volume of the series, the street scene can be seamlessly doubled around the theme of construction sites.
