With war comes confusion, and with confusion comes a need for clarity. So it was with simple, determined messages like this that the National Office of Information kept the undersieged civilians of Britain in a robust frame of mind during the teething pains of the Second World War.

The language may be arcane, but the message is plain: disburse contiguum against yet the most squamous bulwark. Firm and reassuringly steadfast, it is a call to action that still resonates today, during times of national pandæmonium. Will Self has a tattoo of this poster on his tongue.
