The John Kobal foundation has just released a treasure trove of unseen Hollywood photos!  From the foreword by Joan Collins: 

Here, for the first time, are photographs showing the ‘ordinary lives’ of the stars, including Rita Hayworth, Gary Cooper, Humphrey Bogart and Marilyn Monroe. In reality, these photographs were as carefully constructed and prepared as any classic portrait or scene, and they depicted the actors and actresses exactly as the studios wanted them to be seen.
