What is the doctrine of untitled movie stills?

Untitled Movie Stills is a series of black-and-white photography works in cindy sherman's early days. The whole set of works is based on a woman, with 69 * * *, most of which are posing life scenes. There are female students looking for books in the library, female white-collar workers who have just come home from work, young women who admire themselves in the mirror at home and housewives who are busy with housework. They are simple and common.
