How long has charlottes web been out on book shelves

It's amaving how long has charlotts web has been captivating young and old lives.I mean this book has little problems that little kids can worry about, like Wilbur misses Fern. Or it could have a problem as big as the cycle of life.Things die every day but every thong stays the same. It's like EB White was hoping that when people read this book over and over again then every time they dig deeper and deeper into the book we find new reasons we loved it so much when we read as kids.Even though this book is only found in the childrens section doesn't mean it's for children. How many kids do you know that learns about death in second grade. These are the things that makes more like an adult book.It's odd I think of the book itself charlottes web as a child who is very precocios for it's age. And more like an adult then it thinks.
