An EXTREMELY Rare drop from the Exar Kun Heroic instance. Worth over 500 Million credits on most servers.
(As of January 2009, last mural sold for 2 billion on the Bloodfin server and last one offered on Starsider didn't get any bids with an 800 million min bid)

It is a scaled down version of the painting in the room where you fight Exar Kun.

Only a few have ever dropped, which justifies its rarity.
