Comic Identification: When did Hulk have a beard?

I'm not sure if this is even real or not - a friend just posted it on facebook. He's not a comic reader though, just liked the image I guess.

Anyone know if this is from an actual story arc and which one? I've never seen Hulk depicted like this with a beard. Even in Old Man Logan he didn't look this way. Could very well just be fanart but thought I'd ask.
