Amazon Prime is currently streaming a fascinating documentary called “Secrets of the Mona Lisa”… it describes in detail a current theory among art historians
that Leonardo Da Vinci may have painted two versions of his legendary portrait, the Mona Lisa – the first in Florence in 1503 – the second (the famous one on
display at the Louvre) in France around 1516… here are two images – the first is a possible candidate for the 1503 original – the second is the one we all know
and love... these are followed by a handful of related chip images.
