Drapery study 

This pencil sketch by Victor Müller, a German artist active in the 19th century, is a detailed study of drapery. The drawing, housed in the Städel Museum, depicts a piece of fabric in a realistic manner, capturing its folds and textures with precise lines. Such studies were common practice for artists during this period, serving as exercises to improve their understanding of light and shadow, as well as the human form.
