This is a poster that was produced by the Ministry of Information in 1939 and was to have been used if Britain had been invaded by the Nazis. We weren’t, so it wasn’t! However a copy was rediscovered in 2000 (read about it here) and has since gone on to be quite popular.
Despite the fact it’s a very ‘British’ type of statement (the country’s been invaded, but just get on with life!), it is a very good concept for life in general. A simple yet powerful statement!
