Ernst Nepo‘s Family Portrait (The Keller Family) is considered one of the most important social portraits in Austrian art between the wars. In it, the Innsbruck architect Wilhelm Keller (1886–1934) and his wife Anni stage their social self-image and idea of education through their daughters. On first sight, the painting presents itself as a sharp photographic snapshot. In contrast to previous interpretations, however, the aim here is not merely to observe this style and its pretended spontaneity, but to consider the way the work also indicates new ideas of childhood and youth in the interwar period. What image of the adolescent appears, with the girls Ditta and Dora larger than life in front of the viewer? What role do they have within their family? Moreover, what do the architectural toys indicate?
