Alexander Dargomyzhsky, Composer Konstantin Makovsky (1839-1915)

The picture has something of this: people, portrait, man, leader, elderly, jacket, poet, wear, menswear, mustache, neckwear, outerwear, scientist, writer, facial hair, facial expression.
Perhaps it’s a painting of a man sitting in a chair with his hand on his chin and his right hand resting his chin on his left side of his chin.
