Hah! I'm not an expert on anything! Well, nothing related to this comm anyway.
But to my eye, which is no better than anybody else's mind you, it looks like it's an image printed on the wrapper, not a clear or translucent wrapper. If you look at the curled up bit of wrapper where it is torn, the underside of the wrapper is green, even where there is a brown surface below it. If it was translucent, you'd expect to see through it there, too.
I'm thinking there was just an image of the bar printed on the wrapper, and it got torn off half way along the image.
