Avatars within a statue, not statues that look like a Avatar, help!

I was wandering around the otherday and found a few Avatars that were sculpted into a stationary statue. Like the typical non-Avatar statues you see alot but with a AV inside them. I been going crazy trying to find them. Right clicked it but it gave me the unknown/unknow as far as inspecting it. Anyone know where I can get these?
