Large old painting of a mature man - Oil on canvas 19th century / early

Magnificent and expressive portrait of a man from the era (late 19th / early 20th century), created in oil on canvas. The work depicts a mature man with salt-and-pepper hair, sporting an elegant forked mustache and a goatee, dressed in a dark jacket and a starched white collar. The piercing and benevolent gaze gives this canvas a strong decorative presence and a deeply human dimension. Details: Presence of a subtle handwritten signature or monogram at the bottom, indicating the hand of an artist. Style: Ideal for infusing a warm, elegant atmosphere rooted in history into your decor (curiosity cabinet style, bourgeois style, or to contrast in a contemporary interior). Condition: An antique piece in its original state showing signs of time, notably a visible scratch/scrape on the upper left part of the dark background (visible in the photos), which attests to its authenticity and history.
