Head of a man 

This is a portrait of an older man, likely a self-portrait, painted by Polish artist Jacek Malczewski, known for his symbolic and melancholic style. The subject's piercing gaze, combined with the dark background and the artist's characteristic thick brushstrokes, adds a sense of depth and intrigue to the work, inviting viewers to contemplate the sitter's inner world. While the exact date of the painting remains unknown, it likely dates from the late 19th or early 20th century, a period of artistic experimentation in Europe.
