The Department of Public Information, or DPI, is a branch of the Floridian government responsible for distributing propaganda when necessary. The DPI officially came into being on April 15, 1973.
"Keep calm and aim for the head." (Parody of the famous British government slogan in WW-I. Has achieved iconic status in Florida.)
"Re-dead the un-dead."
"An armed citizen is a safe citizen."
"Kill Zomb'!" ("Zomb'" is Floridian slang for "Zombie")
"Fight the undead - aim for the head."
Here is an assortment of DPI posters:
