I think once the "face", (Angus Young lead guitarist for AC/DC), is moved down below for the lower playfield, the game will look much better. It's likely the original design anyways. The Pro version is kind of like the Costco version anyways, just like Iron Man Pro and BDK Pro. Those versions are not on most collector's radars, so who cares?
And no Youssi didn't dream this face artwork up, it's been around for a long time now.
