It's quite clear whence the artist got the idea which elevates my level of respect on its execution since this person obviously knows a thing or two about Porsche history...ready? look at the images below from the pages of "Project 928."
but what of the rear you may ask, isn't that pretty original? no. it's merely a copy of the front in theory, the question really becomes one of why the back end received this kind of treatment which is subject to further explanation. but I won't get into it any further because frankly this sort of shit will become a waste of my time.
