[Attention Surplus Disorder]

What is (or do you suppose) the black, turd-like item is; slanted, leaning north by northwest, directly in front of the shooter's forehead, partially obscured by the rifle's 'carrying handle'? (And pls forgive me if I mis-state the name of the rifle part)

This element is lit "all around" and to me is the most incongruous/evidence of clumsy, 1940's "cut-and-paste" item in the pix.

Looks like a garbage bag draped on the kid's shoulder.
