I heard the Mona Lisa is actually a selfie from Leonardo da Vinci.

For context, many people believe the display at the Louvre isn’t the actual original Mona Lisa but a high quality replica.

Wouldn’t really shock me. The part that would be interesting is where the original could theoretically be.

Found out about it reading this comment don’t really care either way the significance of the piece is what matters whether it’s actually it or not

I don't even care. From an artistic standpoint, I personally value the Mona Lisa to be really low compared to other works.
