A wante poster (or wanted sign) is a poster put up to let the public know of a criminal whom authorities wish to apprehend. They will generally include either a picture of the criminal when a photograph is available, or of a facial composite image produced by a police artist. The poster will usually include a description of the wantee and the crime(s) with which they are charged. Wanted posters are usually produced by a police or other public government body for display in a public place, such as on a physical bulletin board or in the lobby of a post office, but in ages past wanted posters have also been produced by vigilante groups, railway security, private agencies such as Pinkerton, or by express companies that have sustained a robbery.
