Here is a program cast sheet of a performance of the American opera Mourning Becomes Electra by Marvin David Levy. It is signed by the composer (the top autograph in the center), as well as by soprano Evelyn Lear (the bottom left autograph), bass John Macurdy (the autograph on the right side), and the director Michael Cacoyannis. The performance took place at the Metropolitan Opera House, New York City on December 19, 1967. The program page is in great condition, and it measures approximately 8 x 11 in. It is less common to have the composers signature on program like this with the singers. Don't pass this one up.
