The First Thanksgiving (c1912) by the American painter Jean Leon Gerome Ferris (1863-1930).
Ferris shows here a scenery very popular in American culture and iconography. In autumn of 1621 the surviving Pilgrims celebrated their successful harvest and invited the Indians who helped them before with food.
The scene is heavily romanticized. The Indians there didn’t wore feathers in their hair, but they look more "Indian" with that. And as savages that are sitting on the floor, which they wouldn’t have done. So it’s despite all the nice colorful details nothing authentic.
