The simplicity of this box is reminiscent of the work of Minimalist artists, like Donald Judd or Carl Andre. However, Beuys felt that Minimalist art was too far away from the disorder of real life. Yet, in the same way that Judd and Andre made industrial materials look beautiful, Beuys's work was also directed by his love of materials and desire to explore their properties. Here, the neatly cut felt acts as a soft, organic buffer between the sheets of copper. It may be the material's insulating properties which provide the sculpture with its name.
