Föhnwolke c. 1931

Karl Wiener's "Föhnwolke" (c. 1931) is a striking charcoal drawing depicting a dramatic sky. The artist, known for his atmospheric depictions of nature, captures a swirling, ominous cloud formation. The cloud's shape is reminiscent of a swirling vortex, lending a sense of dynamism and energy to the piece. The artist's use of shading creates a sense of depth and volume, bringing the cloud to life. The faint outline of a rooftop in the foreground anchors the composition and provides a sense of scale. This artwork, characteristic of Wiener's style, serves as a powerful illustration of the artist's fascination with the forces of nature.
