¨This painting reveals more about prejudices in Spain at the time .
¨A mother with snow-white skin, a dark-skinned father and a daughter with skin tone in between the two appear as prosperous and well-dressed.
¨But the title of the portrait is curious: "De Espaniol y Albina, Torna Atras" -- literally, "From a Spaniard and Albino, return backwards."
¨The prevailing theory at the time was that albinos were thought to be part African.
¨So the union of an albino with a Spaniard was actually seen as a step backward, towards African heritage.
