Posters (actually broadsides, initially) have been displayed in Great Britain since the late 1600s. They became indispensable during election periods in Great Britain in the second half of the nineteenth and early twentieth centuries, when many more people were enfranchised, especially after the Labour Party was established in 1906.
The BBC has assembled a group of posters, shown to "illustrate David Lloyd George's political fame ad notoriety," put together on the 150th anniversary of George's birth. The posters range from 1910 to 1929—a period when posters were the paramount medium of political propaganda, and when they were often highly imaginative and printed in eye-catching colors from lithographic stones.

George's Liberal Party regained power in 1906. The Liberals "rebranded" their party as one that was more in favor of social reform, and "New Liberals" such as George advocated for legislation to protect and help children, workers, and the unemployed.
George was Prime Minister between 1916 and 1922, which included his leading a coalition government during World War I, followed by his becoming the Leader of the Liberal Party in 1926, a post he held until 1931.
