Wish I could give this 10 stars. I discovered this book as a preschooler in 1968. My mom would take me to the local library every week. I checked it out from the library and I was hooked. I wanted to check it out at every visit, so my mom had the library order a copy for me. I remember even before I could read the words, I completely understood the story from the illustrations. I still have that original edition. It is tatered but still intact. I bought another copy this year for my preschool sons. They absolutely love it as well as the other Scarry book I had as a child, Busy Busy World. The newer book is the abridged edition. The abridged edition has 63 pages as compared to the ~95 pages in the original. They removed 4 stories from the original: busy (stay at home) mom, water treatment plants, electricity and how we get it, and Sgt. Murphy the Busytown policman. Why? Somebody at the publisher must have had a lobotomy. Anyway, we keep the original up in a closet to read only with adult supervision. The new one is on the shelf, readily accesible to the kids.
This book (even the abridged edition) is an absolute classic.
