Something to look at....
I wondered if it really is the mona lisa... so I took a look into ultima omega, and I noticed something different... Mona lisa has no hand as shown in the bottom part...
ultima showed a different image, which is actually the mona lisa.
(名画のレプリカ)="Replica of the masterpiece"
The top part is the actual image as shown within the game...
The other one seems to come from the int-bonus disc.
the other images also seems to be changed
