[Closed] How does a rare painting go “missing”?

Hasn't the Louvre just opened in Dubai? I wouldn't be at all surprised if it turned up there.

I suppose rare in the sense that the artist finished very few paintings. Compared to someone like JoLoMo who reckons he knocks out 3000 paintings a year (in almost the same breath as complaining than non of them end up in national collections)

I was being a little facetious.

I meant, how can a unique work of art (where all original works of art are unique) be anything other than rare, or even more pedantically, it can't be rare, it's just unique (where rare suggests there are very few but still more than one).
