Bunny Brown and his Sister Sue

"Bunny Brown and his Sister Sue" follows the adventures, adorable antics and delightful chatter of Bunny Brown, a 6 year old happy little boy, and his Sister Sue, a lively 5 year old little girl. First published i 1916, this series comes from the popular children’s books publisher the Stratemeyer Syndicate.
Laura Lee Hope was a pseudonym used by the Stratemeyer Syndicate and its successors, most famously associated with the Bobbsey Twins children's novels. Created by Edward Stratemeyer, the Stratemeyer Syndicate was the first book packager to have its books aimed strictly at children, rather than adults. Wildly successful, the Stratemeyer Syndicate was at one time believed to be behind the overwhelming majority of books read by children in the USA.
