No sig on the back?
I know Lee Bradley has been doing some like that, although, doesn't look like it though.. Seems like he either does the Martians or I've seen a few black figures getting struck by lasers although.. he pretty much signs it Lee Bradley so, that would be too easy.
Definitely shouldn't be Jason Adams since everything he does is pretty much a stencil. Although, maybe Jason Hughes surprised us by not dumping ink on a card for once.
