A nice idea, but rather pointless considering we can get the Titanium version at a tenth of the price. And in colour, too.
Looks like the one produced by Monolith Designs: http://www.monolithdesigns.com/toy/main.htm A better description inclusive of the figure's origin could sell that piece. Judging from the manufacturer's past figures, it's probably better than that quality control nightmare, Tit. Prime.
