A Russian woman upset with not having been granted French citizenship threw a coffee mug at the Mona Lisa a little over a week ago, but the masterpiece, dubbed the most famous painting in the world, was undamaged, the Louvre museum said on Tuesday.

According to the Guardian, the woman brought an empty mug into the museum on Aug. 2 and threw this at the painting. Enclosed in bullet-proof glass, the Mona Lisa was untouched.

The woman surrendered peacefully to authorities and later said she was frustrated at not having been granted French citizenship.

It is not the first time someone has tried to wipe off the enigmatic smile from the Mona Lisa, created in 1503 by Leonardo Da Vinci. The $700 million painting was stolen from the Louvre in 1911 but secured two years later after the arrest of a museum employee who wanted to return the artwork to Italy. In 1956, it was damaged when acid and a rock were thrown at it by vandals during separate incidents.
