Cropped publicity still of Bette Davis in the 1934 American film <i>Of Human Bondage</i>. Such images were taken by a studio photographer, and then disseminated to the media and the public to promote the film (see <a href="https://en.wikipedia.org/wiki/Film_still" class="extiw" title="en:Film still">Film still</a>). This is definitely a publicity still due to the high quality of the image.
