Not sure how it can be interpreted any differently, but please give it a shot.
Not sure how it can be interpreted at all, blurry as it is. Some moron DESCREENED it -- yes, I am shouting. It makes my eyes hurt; I try to focus, but there is no sharp image to focus on!

Most importantly, the part of the wing proximal to the elbow isn't visible.
