Francis Dukinfield Astley John Collier (1850-1934)

The picture has something of this: people, portrait, mustache, man, facial hair, leader, neckwear, menswear, vest, royalty, goatee, jacket, cravat, wear, writer, scientist.
Perhaps it’s a painting of a man with a moustache and a moustache on his face, wearing a brown suit with a white shirt and black bow tie.
