It's a fake. The shadow of the engine nacelle on the fuselage exactly matches the curvature of the engine nacelle... but it falls on a curved surface, which should distort the shadow. In addition, the shadow does not match the angle shadows on the engine nacelle itself showing that the light source is different on the engine nacelle and on the fuselage but cannot be both since the light source on the engine should be making the shadow.
To me, it looks like the fuselage is a flat surface.
