Publisher's Synopsis
Grandpa Mac is very old, and full of weird and wonderful tales. Anna loves his strange stories about what the world was like in the olden days, and why things are like they are. In this tale, Grandpa Mac goes on to talk about the time before cars. Wow! There really was a time when cars didn´t exist! And nowadays, we are used to a little green man helping us to cross roads safely, but where did he come from?
