When I went to public school in the 1950s there was always a reproduction of Gilbert Stuart's unfinished "Atheneum Portrait" of George Washington in the classroom. These "before" and "after" photographs are of a painting which hung in a schoolhouse built in 1841. The painting was signed by an unidentified French artist who might have copied a Stuart original, and the painting apparently hung in the building from the time it was built. The painfully difficult filling and color matching were beautifully executed by Anthony Graves.
