George C. Parker's Deed to the Brooklyn Bridge

Origin
George Parker (1870–1936) was one of the most audacious con men in American history. He made his living selling New York's public landmarks to unwary immigrants. His favorite object for sale was the Brooklyn Bridge, which he sold several times. He convinced his marks that they could make a fortune by controlling access to the roadway. More than once police had to roust naive buyers from the bridge as they tried to erect toll barriers.
