Hello hello, does anyone have a better picture of the yellow "Lava Comic" T-Shirt?
What does it actually say?

It says "Soon the Lava will rise" and depicts JB with a giant tap in his hand, probably about the impale a sleeping woman with it.

If you've got the Lava single (the one with the Fifteen and Tokyo E Ikatai) it is the same hand and tap from the cover.

Welcome, Mr/Mrs/Ms Damagedlemons!

I own one of those very shirts - it's what every fashionista will be wearing come summer...
