Jan Anthonisz van Ravesteyn (and studio) – Portrait of an Officer Mauritshuis

The picture has something of this: armor, sword, people, knight, wear, portrait, weapon, man, Renaissance, helmet, veil, war, jewelry, skirmish, soldier, jacket, Gothic.
Perhaps it’s a close up of a painting of a man with a beard wearing armor and holding a sword in one hand and a glove in the other hand.
