Well, not to quibble with you, but any legitimate 
reproduction of the Mona Lisa must be approved by 
the Louvre.  They aren't going to be "happy" in 
any sense of the word if you buy an unauthorized 
poster print or a hand-painted reproduction.

Personally, I intensely dislike fancels that are 
repros of existing cels, whether they are made 
from screenshots or swiped cel scans, because 
they reek of unoriginality, laziness, and deceit.
