From the striking 'Labour Isn't Working' posters of the 1970s to a demonic Tony Blair, political adverts have always impacted on the public.
Now a new book, Dole Queues and Demons, chronicles the evolution of Conservative party advertising over the years and allows an insight into how the issues of the day have changed - and with it, the social attitudes of Brits.
In a forward to the book, advertising guru Maurice Saatchi says posters are to politics "what poetry is to literature: the only possible words in the only possible order. They should instantly convey the core message in a memorable way. This requires a handful of words, each of which is perfectly chosen, married to an image which reinforces them. When this happens posters can be the single defining medium of a campaign."
See below for a selection of images taken from the book.
