caption: The image shows a black and white drawing of a man standing on top of a building, with a wall and a ladder in the background. At the bottom of the image, there is some text which reads "Thomas Gainsborough's plans for the construction of the tower of London". The man is wearing a long coat and a hat, and is holding a sword in one hand and a shield in the other. He is standing in front of the wall, which is made of stone and has several arches and pillars. The ladder is leaning against the wall and is used to climb up the wall.
