Italian stage and film actress (1908-1973), English film actor producer, director and screenwriter (1882-1974), and Irish actress and singer (1920-2015). 

All three of their signatures are on the front cover of a full playbill/program for a 1955 Broadway production of Gian Carlo Menotti's opera The Saint of Bleecker Street (although they did not themselves appear in this production). Full program including all pages and covers, size is 6.5 x 9 inches, in very good condition.
