Rudolf Gudden's charcoal drawing "Ein Pfeife rauchender Mann auf einem Hügel rastend, angelehnt an einen Esel" depicts a man resting on a hill, leaning against a donkey while smoking a pipe. This simple yet evocative sketch, housed in the Städel Museum, showcases Gudden's mastery of line and form, capturing the essence of a quiet moment in the countryside.
