In the new storybook, Christopher Robins along with Pooh bear, Piglet and Eeyore sets off for London to give the Queen a special present for her birthday. On their way to the Buckingham Palace, the group wonders at the amazing sights of the city such as the Trafalgar Square and the iconic Big Ben. Just outside the Palace, they meet Queen Elizabeth II who was depicted with a red coat and hat, as well as the royal monarch’s familiar black gloves and black handbag, as stated in the same report.

Prince George also made an appearance in the new “Winnie the Pooh” storybook. The royal toddler was drawn wearing blue shorts and a blue cardigan over a white-collared shirt. In the book, the Queen’s great grandson was described as “almost as bouncy as Tigger” and “much younger than Christopher Robins.” Prince George was even given a red balloon by Piglet in the new “Winnie the Pooh” adventure story.

The story for “Winnie the Pooh and the Royal Birthday” was written by Jane Riordan and the storybook’s illustrations were drawn by Mark Burgess. The illustration in the said new storybook was said to be drawn in the classic E.H. Shepard style. In an exclusive sketch provided to People magazine, Burgess has also depicted Pooh and Piglet playing ball with some of the Queen’s beloved corgi pets with the Buckingham Palace in the background.
