The image shows a zoo enclosure with a red metal structure on the left side and a wooden fence on the right side. In the center of the image, there is a large rock with a white gorilla on top of it. The gorilla is standing on its hind legs and appears to be climbing up the rock with its front paws. On the ground next to the rock, there are two smaller monkeys, one black and one white. The background shows trees and a clear blue sky. The image appears to have been taken in the early 20th century.
