The picture is credited with encouraging millions of men to sign up to fight in the trenches, many of them never to return.
But new research has found that no such poster was actually produced during the war and that the image was never used for official recruitment purposes. In fact, it only became popular and widely-used after the conflict ended.
James Taylor, who has researched the history of recruitment posters, said the popular understanding of the design and the impact it had was almost entirely mistaken.
