It's from 1656, and it's called "Las Meninas," and it's the picture of a little princess and her ladies-in-waiting, and if you look over that little blonde princess's shoulder, you'll see a mirror, and reflected in it are her parents, the King and Queen of Spain, who would be standing where you might stand to look at the picture.
Es de 1656, y se llama "Las Meninas", la pintura de una princesita y sus damas de honor, pero si miran detrás del hombro de la princesita rubia, verán un espejo, y en el reflejo están sus padres, el Rey y la Reina de España, parados en el lugar en el que nos pararíamos para ver la pintura.
