World War I was arguably the first time that posters were used for mass propaganda purposes.
The majority of WWI posters focused on recruitment, which was necessary due to the massive casualties in battles, such as those at the Somme.
Posters focused on themes such as working on the Home Front
Other posters focused on themes such as lending to the government via bonds, or working on the Home Front.
The soldier is the most commonly-found motif, with the early enthusiastic soldier giving way to the more restrained image of a soldier bravely holding the trenches as the war progressed.
This 1914 British recruitment poster designed by E J Kealey is valued at £120-£180.
