Photo booth pictures of Truman Capote, Audrey Hepburn, and Mel Ferrer, c. 1956.
"Marilyn [Monroe] was my first choice to play Holly Golightly. I thought she would be perfect. Holly had to have something touching about her…unfinished. [But] Paramount double-crossed me in every way and cast Audrey." - Truman Capote
Personal note: Capote: A Biography by Gerald Clarke is the biography that made me a fan of biographies.
