I stopped to ask him about the tattoo. Or rather, asked him if I could take a picture, when he revealed that it was much larger than it appeared poking out of the sleeve on his left arm:
Sadly, I gave him the Tattoosday flier and asked him to e-mail me so we could discuss it further and he a) lost the flier or b) decided to forgo contacting me. So, I have no idea who he is, nor can I credit the artist, whose work is pretty darn impressive.
When this happens, I dub it an "orphan" post, but obviously, despite the lack of details, it's still worth sharing.
Thanks to the anonymous contributor who allowed me to take photos of this great tattoo and share it with us here on Tattoosday!
