A wanted poster (or wanted sign) is a poster distributed to let the public know of a person whom authorities wish to apprehend. They generally include a picture of the person, either a photograph when one is available or of a facial composite image produced by the police. Description The poster will usually include a description of the wanted person(s) and the crime(s) for which they are sought. There is typically a set monetary reward offered to whoever catches the wanted criminal that is advertised on the poster. Wanted posters are commonly produced by a police department or other public government bureaus intended for public display such as on a physical bulletin board or in the lobby of a post office. Today many wanted posters are displayed on the Internet. However, 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. Wanted posters also might include rewards for providing aid in the capture of the wanted person, usually in the form of money. These types of posters were also referred to as reward posters. Electronic billboards In 2007, the FBI began posting wanted posters on electronic billboards starting with 23 cities, and have been working to expand this system in other states. This allows them to instantly post a wanted notice in public view across the US. In 2014, the FBI claimed that at least 53 cases had been solved as a direct result of digital billboard publicity, and many others had been solved through the Bureau's overall publicity efforts that included the billboards. The FBI now claims to have access to over 5,200 billboards nationwide. Bounty Wanted posters for particularly notorious fugitives frequently offer a bounty for the capture of the person, or for a person who can provide information leading to such capture. Bounties provided an incentive for citizens to aid law enforcement, either by providing information, or by catching the criminal themselves. More modern wanted posters may also include images of the fugitive's fingerprints. People who, as a profession, chase wanted individuals with the intent to collect their bounties are referred to as bounty hunters.
