Camels at the Fountain Jean-Léon Gérôme (1824-1904)

The picture has something of this: mammal, people, group, cavalry, camel, sculpture, man, vintage, seated, transportation system, desert, lithograph, wear.
Perhaps it’s a painting of a desert scene with camels drinking from a watering hole and a man with a hat on his head standing next to a group of camels.
