Auguste Couder – Oath of the Tennis Court (Oath of the Jeu de Paume), 20 June 1789 Château de Versailles

The picture has something of this: people, group, many, crowd, man, woman, music, military, performance, wear, soldier, group together, audience, child, dancing, recreation.
Perhaps it’s a painting of a man standing in front of a crowd of people with one hand up in the air and his other hand.
