In The Outskirts of Cairo Peder Mork Monsted (1859-1941)

The picture has something of this: people, group, many, palm, camel, mammal, man, beach, woman, tree, desert, landscape, oasis, sand, tourist, daylight.
Perhaps it’s a painting of a desert scene with a group of people in the foreground and a man on a horse on the far side of the picture.
