The image shows a black and white engraving of a group of people in a room with a man and woman standing in the center. The man is holding a book in his hand and the woman is holding an object in hers. There is a pot in front of them and a few people sitting on the right side of the image. At the bottom of the picture, there is some text which reads "William the Conqueror and Mary Magdalene".
