With his series Lessons in Posing Subjects, Heinecken used a Polaroid instant camera to re-photograph images in clothing catalogues and presented them as typologies of body positions and facial expressions. Building on Erving Goffman’s book Gender Advertisements (1976), which explored how commercial advertising both reflects and constructs our concepts of masculinity and femininity, Heinecken’s mocking sociological study of mass-media imagery similarly reduces standard fashion poses to repetitive symbolic gestures. The cultural values communicated by each stance are humorously explicated in the dry tone of a textbook.
