Portrait of a Man 

Frank Duveneck's "Portrait of a Man" is a striking example of his signature Realist style. The painting, rendered in a dark palette, captures the subject's weathered features with incredible detail. Duveneck's loose brushstrokes create a sense of immediacy, highlighting the man's worn clothing and the raw emotion in his gaze. The contrast between the dark background and the man's illuminated face draws the viewer's attention to his character, echoing the themes of social realism that Duveneck explored in his art.
