Round Trip by Ann Jonas

I found this book on a list of maths books for small kids on the great blog What Do We Do All Day. Check it out.

Round Trip is a day out in the city, New York City, I'm pretty sure. It starts at home, journeys into the metropolis and then, at the end of the day, you just turn over the book and drive home. Each illustration makes sense from both perspectives. Its very clever.

and from the other direction...

Cool, isn't it? For ages three and up.
