Portrait of George Washington - Could a portrait passed down through a Frederick, Maryland, family actually be an authentic portrait of the nation's first president, George Washington? That is the charge for HISTORY DETECTIVES in this fascinating story. The investigators attempt to prove whether or not the famed artist Gilbert Stuart, whose resume includes the portrait of Washington that appears on today's dollar bill, was the artist behind the drawing in question. Might this drawing prove to be a national treasure? Revolutionary War Poem - HISTORY DETECTIVES goes to Salem, Oregon, to look into the story of a Revolutionary War poem found 25 years ago hidden in an antique trunk. The document appears to have been written by an American named Dan Goodhue while imprisoned in 1780 as a POW in England. Who was this man and how did his poem travel for over two centuries, across the sea and nation, to end up in Oregon? Revolutionary War Cannon - A Boston woman is fascinated by an old cannon, kept in a local national park storage facility.
