Two pages from the program for the 1977 San Francisco production of Turandot, matted and framed. The pages are the cover and the cast credits. The cover is signed by Montserrat Caballe (Princess Turandot). The cast credits signed by Luciano Pavarotti (the unknown prince). Both signatures are quite large. On the cast page there are also signatures of performers Leona Mitchell, Giorgio Tozzi, and Robert Johnson, but these have faded somewhat or are impressions from signatures on earlier pages.
