What was the first authorized Winnie-the-Pooh sequel published after A. A. Milne’s death?

Return to the Hundred Acre Wood was the first authorized Winnie-the-Pooh sequel published after A. A. Milne’s death.

The book appeared in 2009 and was written by David Benedictus, with illustrations by Mark Burgess in the style of E. H. Shepard. It continued the adventures of Pooh and his friends while remaining separate from Milne’s two original story collections.

Milne’s own Pooh books are Winnie-the-Pooh, published in 1926, and The House at Pooh Corner, published in 1928. Milne died in 1956 and did not write another full Pooh story collection.

The word “authorized” matters because many Pooh adaptations and licensed products existed before 2009. Return to the Hundred Acre Wood was specifically presented as an officially approved literary continuation.
