I would love to have one, do they exist?

For now one can make do with one of these :

go on ebay and search DT there is a guy to make a shirt one its black and has the Paolo Parente Dust on it.

I got a shirt as a prize at the GenCon tournament

The artists at FFG are top notch, they should produce an apparel line for a their most popular games. Something like what GW does with their shirts.
