Portrait of Doctor of Medicine and Surgery Nikolai Fyodorovich Arendt Iosif Oleshkevich (1777-1830)

The picture has something of this: people, wear, portrait, man, outfit, leader, neckwear, menswear, business, outerwear, administration, jacket, sitting, music, facial expression, two.
Perhaps it’s a painting of a man in a black suit with a red and white flower on his lapel, sitting in front of a pillar and cloudy sky.
