The Classical Theater of Harlem, certainly put on a performance using " elaborate white cardboard masks" in 2003 as well as the 1961 long running off-Broadway production with James Earl Jones.
I think the latter production however was the first using an all black cast: the original production Les Negres: Clownerie (The Blacks: A Clown Show) was first produced at the Theatre de Lutece, Paris, 1959.
