Colonel Francis Brockman Morley John Collier (1850-1934)

The picture has something of this: people, wear, portrait, outfit, royalty, leader, man, military, sword, theater, pants, ceremony, weapon, veil, award, administration, military uniform.
Perhaps it’s a painting of a man in a red uniform standing in front of a red carpeted area with a red chair and a red curtain behind him.
