Here is a nice Metropolitan Opera program cast sheet from a performance of Verdi's Don Carlo dated June 21, 1972. It is signed by four of the principal singers, Giorgio Tozzi, Nell Rankin, John Macurdy, and Elinor Ross. Tozzi was the Philip II for the night's performance. Nell Rankin sang the part of the Princess of Eboli. Grace Bumbry, the originally scheduled Eboli, sang the first two acts of Don Carlo, then Rankin took over for her for the last two acts. Franco Corelli, Robert Merrill, Frederica von Stade, and Paul Plishka were also in the performance. It is in great condition. There are no tears or creases. It is approximately 8 x 11 in.
