This was posted on a FB FF group, but the poster had just found it online. I can't make out the signature, did a google image search and scoured Deviant Art but no luck. Even cleaned it up in photoshop to try and make out the signature (Zane Meteals? that's not it) but no luck. Very Turneresque but it's not his. That's an AWESOME Ben Grimm with the functional unibrow look and Johnny with the classic Kirby lines. I'd love to find out who did it to see if I could get a copy from them.
It is a nice picture. It reminds me a bit of Pelletier. Looks like Reed is about to corral Howard the Duck before it clobbers Ben.
