The piglet at the Getty was part of an exhibition which has closed and isn't there any more. I believe it was lent from the Museo Archeologico Nazionale, Naples.
Here's a link to the exhibit: http://www.getty.edu/art/exhibitions/villa_papiri/index.html
They also had a little head of Epicurus, from the same museum in Naples. There's a great photo of it in the middle of this page (2D of course...): http://www.getty.edu/art/exhibitions/villa_papiri/inner.html
The best bet might be if someone can get to the Naples museum with a handheld scanner. They might not allow that in the best of times, let alone in our current pestilent state ![]()
