The image appeared in the backstage of a portrait of the monarch.
Last week, Isabel II revealed her new portrait, however, and as the international press notes, the Queen forgot to remove another photograph from the background in which appear the grandchildren George, five years old and the princess Charlotte, three.
As Hollywood Life reports, the image is already old and taken before the birth of little Louis. In it, Charlotte appears to be on the queen's lap while George appears between her and her husband, Prince Philip.
