caption: The image shows a drawing of a man standing in front of a door with a door handle, surrounded by a white background. At the bottom of the image, there is some text which reads "Victor Vasarely's drawing of the door mechanism". The man is wearing a long coat and a hat, and is holding a hammer in his right hand. The door handle is made of metal and has a curved shape with a handle on the top. The wall behind him is plain and unadorned.
