must-be-the-monet:

Eduoard Manet
Olympia, 1863
French, the Louvre 

I got to see this in the flesh.  I almost broke down and cried.  Trust me, I had 50 of these moments inside Musée d’Orsay.  And yes, the information listed is incorrect.  This one is NOT in the Louvre.  If it was, I would have taken a picture of it.
