Verena Loewensberg's abstract paintings are always untitled in order to avoid any misleading, narrative interpretation. Given the understanding of art of the Zurich Concrete artists, of whom she was one of the main representatives, her graphics and design works are on a par with paintings. The graphic edition shows four squares of concentrically arranged rectangles. When viewed, the colorful areas of color have an iridescent effect and set the firmly joined picture composition in dynamic, circular oscillations.
