PhillyBurbs.com has the news that despite Stan Berenstain’s death in 2005, the Berenstain series will continue. Son Mike Berenstain is an illustrator who writes most of the series now. In the article, he talks about how Dr. Seuss changed his parents’ work:
It was Geisel who advised Mike’s parents, Stan and
Jan Berenstain — primarily cartoonists — to make the Berenstain Bears a
series rather than a single book. The couple had intended to write
about penguins next.
