But it's a total send-up...totally fabricated. There is no way this is a legit photo of the era. Bones wouldn't stay attached, they wouldn't stand up vertical (they'd be scattered and flat) and the onlookers, regardless of what they saw, would not be so casual. This is a total send up. But it's reasonably well assembled and retouched. Did you intend this to be a fantasy or did you intend for people to accept it as real. I am uncertain about your intent.
...Sorry to be a Grinch, but that's what I am when I see something like this.
