Mazurski and Bond (1993) reported on the development of a new series of slides of facial expressions of emotion that improved on Ekman and Friesen's (1976) Pictures of Facial Affect. They apparently did not know about another new set which has been available since 1988 that improves on Ekman and Friesen's photograph set, and has many advantages over Mazurski and Bond's set. We describe that set in this article.
