Sure...The shroud is one piece of cloth...It goes from the feet at the front, up over the head and down the back, again to the feet...
Two images on the shroud, one of the front and one of the back...
When layed out straight, the image of the head in the front butts up to the image of the head in the back...Where's the top of the head??? When layed out, there's no space for the top of the head like there would have to be in a legitimate image...What's up with that???
There us a gap between the top and back of the head on the cloth. What you are seeing is just a water stain that makes it appear that the front/back of head meet without a gap. I posted a link to an image that shows it pretty clearly a few months ago. If I get some free time later this evening I'll go find my old post.
