In the picture, a high stone wall can be seen in the background. The stones are quite small and have been arranged four times, two next to each other and two below each other, in such a way that they have formed several ovals. In front of this wall in the centre of the picture is a small tree in a dark pot. To the left of the tree are two men in dark suits talking about istas heat-contracting. The jacket of the man on the left is open, revealing his white T-shirt, and he is holding a document in his hands in front of his upper body. The man on the right, standing with his back to the plant, is carrying a black cloth bag in his left hand.
