This story was featured on Yahoo!News yesterday. It discusses the recent discovery of humans in a Cincinnati waterfront daguerreotype taken in 1848. In the photograph, there are two men standing on the dock located on the left side. The story goes on to compare this discovery with that of the earliest known image of a human in Louis Daguerre's 1838 photo of Paris. In Daguerre's picture, there is a man getting his shoes shined in the lower left hand corner.
