Mashups of the Mona Lisa

  I wanted to grab a picture of the Mona Lisa so I searched for it.

  There are all these mashups of the painting, but where's the original?
    BTW, the painting is at the Musee du Louvre in Paris.
  It's at the center of something, everyone's talking about it, visually, but it's hard to know which is the original and which is the mashup.
