This book is short with only 26 pages. If your looking for a very basic overview then this would be fine but i think people wanting to understand economics will most likely get just as much from reading my blog.

This collection brings back memories from many years ago when we watched reruns together. It was fun to share with our children and grandchildren. We bought it for their children. They loved it, too. Even now as adults, it's nice that they can enjoy it.
