This is photoshopped - in the original she was not wearing lowlegs and the skirt didn't rise up that high - there was no crack showing. Can't find a copy online of this particular reprint, but here's the original with background:

Now that you say it, it becomes very visible in parts... I gotta look out for that.

I only realised because I'm familiar with the original. Oddly I can't remember ever seeing the scan this was photoshopped from anywhere.
