One of it, was this very nice Ezio lithograph from AC Revelations..
This is the art piece, "Revelations" by Craig Mullins. This print was given only to developers and a lot smaller than the UbiWorkshop giclee.
At the bottom, it's stamped with "Ubisoft Team Edition" and limited to 500 pcs.
Also got this Connor Amulet Necklace from Ubiworkshop
and lastly this AC Unity Coin from Loot Crate.
As always, I'm looking for more Assassin's Creed promos and rare stuff. Do drop me a mail or contact me via FB if you have anything rare to sell.
