Quoted from Aurich:

Man, this version is hilarious to me personally, because I've been playing with a little AC/DC side project featuring ... a drawing of a sexy devil lady.
Proper red, not pink, but still, now if I release it it's going to look like I stole the idea from Stern. Oh well, just a little fun thing I was messing with, no big deal.
It's an established style (see stickers and figures above) so it's not really all that funny that they look related, just funny timing.
