Portrait of Count Giacomo Carrara Giovanni Pezzotta (1838-1911)

The picture has something of this: people, portrait, wear, royalty, monarch, queen, jewelry, man, necklace, woman, wig, leader, jacket, outerwear, music, veil.
Perhaps it’s a painting of a man with white hair wearing a black coat and holding a book in his right hand and a red curtain in the other hand.
