The original map of Winnie-The-Pooh's Hundred Acre Wood - "probably the most famous map in English literature" - is expected to sell for up to £150,000 at auction.

EH Shepard's original 1926 sketch, unseen for nearly half a century, introduced readers to the world of Christopher Robin and his woodland friends in the original book.

The wood is visited regularly by the young boy Christopher Robin, who accompanies Pooh and company on their many adventures.

The Hundred Acre Wood of the Winnie-the-Pooh stories is in actuality five hundred acres in Ashdown Forest in East Sussex, England, where the Winnie-the-Pooh stories were set.

The map is due to be sold by Sotherby's in London in July.
