I didn't see that grey line there. It most have been something done by the uploader to the board that I got it from. I'd upload a better version, but I have no idea who the artist is or his website URL. It's a real shame, since he's probably one of my favorite artists.

Just open any picture editor (heck, even mspaint) and cut it off, its not like its on the way of anything.

This is beautiful.
