Love, Mr. J!
Got this piece a little bit ago and figured it was time to post before the onslaught of SDCC.
Joker by Adelso Corona. Adelso is self taught artist - mainly has done ink work in the comic world but his standalone pieces are stellar in my opinion.
Incredibly talented and still reasonably priced. Check out his DA for more of his work:

Apologies for the bad pic - the camera washes out his beautiful ink work.
