Well, it's really odd. I enhanced the photo some. It looks to me almost what you'd make as a prank for someone to dig up. Thos circles within the "ears" are really precise. And I fancy I can see inside them something that looks like propellers(?) that exhibit the bending effect that wasn't ever seen in moving objects until photography was invented. Now, of course, we take it for granted and always use it to show motion. Like the idea of cars distorted and kind of leaning forward with oblong wheels to suggest speed. Prior to photography, where the effect came from an object moving past a vertical shutter, no one would understand it.
(Or maybe it depicts an alien fan driven vehicle. Oops. Better not suggest that. Weird ideas take root too easily with some.)
