Portrait of the Architect Giuseppe Valadier Pietro Labruzzi (1739-1805)

The picture has something of this: portrait, people, man, wear, neckwear, menswear, outerwear, jacket, tie, model, fashion, scarf, dark, light, face, facial expression, studio, theatre.
Perhaps it’s a painting of a man in a blue suit with a white shirt and a white bow tie sitting in a chair with his hands on his chest.
