Es braust ein Ruf wie Donnerhall 

This powerful drawing was made by Karl Wiener, most likely in the 1930s. It's done with ink on paper, a relatively direct method. The artist is using the stark contrast of black and white to convey a strong sense of emotion. The title, "Es braust ein Ruf wie Donnerhall," translates to "A call roars like thunder," suggesting a cry to action. The figure's distorted features and open mouth convey a sense of urgency, even violence. Notice the cross-hatching technique, rapidly applied, creating areas of shadow, to convey the tension. Given the period in which Wiener was working, this image may be a commentary on the political climate, perhaps reflecting the rise of extremist ideologies. The artist’s choice of a readily available medium like ink and paper suggests an effort to communicate a message quickly, accessibly, maybe even to reach a broad audience. Wiener pushes the boundaries of what drawing can express.
