Sigbert Marzynski 

This etching by German artist Max Liebermann, titled "Sigbert Marzynski," depicts a portrait of a man with a contemplative gaze and a slightly downturned mouth. The subject is presented in a simple composition, wearing a suit and tie, with his shoulders slightly hunched and his head turned slightly to the side. Liebermann, a leading figure in German Impressionism, is known for his masterful use of light and shadow, creating a sense of depth and realism in this work. The etching's fine lines and delicate shading capture the subject's features with a sense of both intimacy and objectivity.
