A post-war increase in traffic and therefore road accidents led to campaigns and poster such as this one (1963).
Nothing new in the nanny state.
These nagging posters highlight Britain's 'nanny state' approach to post-war life in an age before television and the internet.
The posters show successive British governments' attempts to control and influence every aspect of the lives of their citizens through visual messages.
They were born out of the state's optimistic view for a post-war Britain in which every family would be properly fed, clothed and cared for.
Dating back to the mid 1940s, the posters were issued by various government ministries and departments with a view to making life better for Britons.
They sought to influence numerous areas of everyday life including health, hygeine, holidays, food, work, pensions, savings and crime.
One poster, titled 'The seven rules of health', reminds people on how to keep clean and healthy by exercising, getting enough sleep and washing.
Published by the Ministry of Health for Scotland in the early 1950s, it advises people to put clean underwear on once a week.
It also urges them to wash all over every day claiming "it takes a bit of time but it's worth it, and so refreshing".
