A Google search out of boredom caused me to stumble on this: the early drafts/concepts for the MTM1 box art. The website is
http://idrawyourcar.com/, and it's the site of a guy, Scott Curtis, who did a bunch of design work for Microsoft in the mid-90s.
The box also pops up on his other, more general portfolio:

I don't know about that M rating, though
