Fancy winning yourself a Sweet Oblivion T-Shirt?

As I sat upon the throne this morning, flicking through a copy of G-Works, I stumble upon this funky old piece of J-Tin..

Even I'm stumped as to what it is. So to win yourself a T-shirt this month all you need to do is identify it.. because it's driving me nuts LOL. The first correct answer posted on the Sweet Oblivion facebook page.. wins!
