The Berenstain Bears and the Trouble with Friends

Stan and Jan Berenstain were already successful cartoonists for magazines and adult humor books when they began writing children's books. The first story starring the bear family, The Big Honey Hunt, appeared in 1962. Since then, more than 360 Berenstain Bears books have been published, and more than 300 million copies have been sold. What began as an idea sparked by their young sons' love of reading has become one of the best-selling children's book series ever.
