Piero (16) Piero della Francesca (1415/17-1492)

The picture has something of this: people, group, engraving, military, many, man, war, cavalry, soldier, skirmish, weapon, vehicle, gun, wear, several, group together.
Perhaps it’s a black and white photo of a group of people in front of a wall with a large painting of a bird on the side of the wall.
