A combination of a stop sign and a certain tobacco company's recognizable packaging. Just made sense to me.

Very clever. It's really simple so it could be a lot of things, a polygonal pacman for example.

a neat idea, but a bit too simple i think. without your explanation it could be anything.

I was going for simplicity but maybe I over-simplified. Perhaps I should try a black T and include the edge of the pentagon to make it more complete.

im pretty sure its gonna be rejected cos of that relation with the real brand..

really clever idea. but it doesn't translate on the shirt
