Mega Man Box: real or Fan Made?

I haven't seen the UK or EU specific boxes, so it could be one of those (seems more like UK given the english text), and I know UK and EU got different art for the later games, so I thought it might be possible, and it does have a similar style to some of th ehigher quality EU or UK box art.
Still, that's pretty detailed and pertanent to the game (compared to UK MM2) so I'm not sure. (though the buster is on his right arm rather than left as the Japanese standard)
A damn good photoshop if it is one.
Edit: nevermind about the left vs right arm thing, it appears the Rockman box/cart art also had it on his right for the first few games at least.
And given this:

It definitely apears to be the UK box art. If it is, that's damn good.
