Here is a nice Metropolitan Opera program cast sheet signed by sopranos Teresa Zylis-Gara and Edda Moser. The performance was of Puccini's La Boheme on the night of March 9, 1974. Zylis-Gara was the night's Mimi, and Moser was the Musetta. It is in great condition, with slight discoloration. It measures approximately 8 x 11 in.
