Portrait of the architect Gaetano Gallizioli Rinaldo Emilio Francesco Agazzi (1857-1939)

The picture has something of this: people, man, portrait, facial hair, wear, music, veil, mustache, lid, side view, exploration, profile, engraving, leader.
Perhaps it’s a painting of a man in a black suit and white shirt sitting in a chair with his hands in his pockets and his right hand in his other hand.
