All promotional literature was designed and printed by the Scarfolk Advertising Agency, who, it was later revealed to the surprise of all clients concerned, had been working not only for the Conservative, but also the Labour and Liberal Parties.
Furthermore, the agency cleverly maximised its profits by selling exactly the same poster designs to all clients. Only the party name was changed. This made it difficult for voters to decide who to vote for, but it also confused politicians who became unsure which party they belonged to.
