The ways in which politicians and political parties have appealed to voters during election campaigns have changed dramatically over the years - especially since the advent of radio and television.
Many of the oldest forms of electioneering are still relevant in the 21st century: the public meeting at the local school or town hall, door-to-door canvassing, advertisements in newspapers, and the use of eye-catching posters, hoardings and leaflets.
Given the printing technology of the time, early election posters and hoardings were inevitably simple. From the late nineteenth century, however, they gradually improved in sophistication to include stylistic flourishes, symbols and photographs of candidates.
But content was still more important than form, and it was common for posters to contain very detailed information on candidates' policies or character.
