A Greenville, Ohio, man was sorting through documents stored above one of Manhattan's first taverns when he stumbled across a miniature color painting of a man in profile labeled "G. Washington." On the back of the portrait, he found the inscription, "Property of White Matlack. New York, 1790." The historic tavern and museum sits just steps away from the old City Hall building on Wall Street where George Washington took his oath of office in 1789. The History Detectives set out to discover whether the artist painted this portrait of Washington from life, and to uncover its surprising connection to the little-known abolitionists and patriot White Matlack.
