People are going to whine if the artwork is photoshopped but the artwork on the original KISS machine wasn't much chop either so this is going to be a hard one for anyone to get right.
Personally, I think they should use a mix of the various album covers and the face painted band members from say 1978 should do the trick.
Then u have to work out which drummer you are going to lead with.

People are going to complain about the artwork no matter what is done.
I think Kiss Pinball will be the biggest whinge fest since the invention of the wheel.

But I hope they make it and hope people love it. Hope it's nothing like the other Kiss pinball which was iconic to look at but was an average player at best.
