Sander?s approach in photographing subjects for his ambitious project `People of the 20th century? was highly methodical and based on an almost sociological analysis of Germany at this time. He divided his portraits into seven main groups. This photograph is from Group Six, `The City?, and the portfolio `Travelling People ? Fair and Circus?. It is an example of Sander?s supreme skill in creating a striking composition. The strong horizontals of the wooden caravan are broken by the delicate, almost ballerina-like curve of the girl?s arm as she reaches out to open the door. Her arm also acts as a device in creating depth, extending from the background into the foreground. The darkness behind the girl?s head frames her perfectly within the image.
