Many of the exhibited postcards focus on the faces of the Professors. The faces almost take up the entire space and appear as if they had emerged from it. By frequently leaving the base of neck and shoulder blurry, the person is fully reduced to countenance alone. This focus is in the tradition of portrait photography of the interwar period. As society changed, becoming more urban and industrialised, many contemporaries feared a loss of the personal. The photographic work on the face, as it was carried out primarily in popular photographic portrait series of the 1920s and 30s, was intended to counteract this impending loss and, via the visage of a person, refocus on the individual itself.
