One of the most Iconic Genre-defining Books of all time is Truman Capote’s In Cold Blood. It heralded the arrival of the Non-fiction Novel.
The 1967 Movie Version of this book has a unique poster. The eyes in the movie poster are actually those of the real-life killers Dick Hickock & Perry Smith (and not of the actors).
The 2007 Film An American Crime is based on the real life murder of Gertrude Baniszewski, a housewife. So, aptly, the poster pays a tribute to In Cold Blood.
