Boulders 

Franz Kobell's "Boulders" is a pen and ink drawing depicting a rocky, mountainous landscape. The artist's skilled use of hatching and shading creates a sense of depth and texture, making the large boulders appear imposing and three-dimensional. The drawing is a testament to Kobell's talent for capturing the beauty of nature, particularly his fascination with the rugged and untamed landscapes of the Alps. The work is housed in the Städel Museum, where viewers can appreciate its detailed portrayal of the natural world.
