Details: This is a warning sign to be placed in areas that you wouldn't want zombies to enter.
A zombie is a mythical creature that appears in folklore and popular culture typically as a reanimated corpse or a mindless human being. Stories of zombies originated in the Afro-Caribbean spiritual belief system of Vodou, which told of the people being controlled as laborers by a powerful sorcerer. Zombies became a popular device in modern horror fiction, largely because of the success of George A. Romero's 1968 film Night of the Living Dead. Modern zombies are typically depicted in popular culture as mindless, unfeeling monsters with a hunger for human brains and flesh. Generally these can only be killed by a wound to the head, such as a headshot, and can pass whatever syndrome that causes their condition onto others.
