The series “Key Operators” focuses on the examination of immaterial work and the material handling of paper, which serves as a carrier of information, ideas and modes of representation. The watercolours and prints are based on stock images, generic material from image databases produced and used for illustrative purposes in advertising and the press. They depict people, primarily men, in office situations. By handling paper, computers and printers, they suggest cognitive but repetitive work. The devices are part of the image as watercolour depictions of the concrete technical machines as well as the result of their use. The pictorial space is additionally expanded by to scale prints of hands and their silhouettes, implying work taking place in the background. Certain works consist of watercolour on paper, others have additional inkjet-printed sections.
