Thanks Lee! Yes, it looks like it... but he clearly has others there too above the dragonfly. I'm in the midst of telling a friend of mine in Pittsburgh about various aspects of Heath because of the Dark Knight stuff going on here. And, the tattoos became a subject of discussion.
We're going to have a Dark Knight viewing session tomorrow. The filming going on here in town is making me have a renewed sense of nostalgia for Heath (combined with the major fact that I watched BBM again recently).
