I'd be very surprised if it was legit. I've looked over the pictures and couldn't find any "tells"  that they are faked, yet. About 6 guys carrying each box like it weighed 300+lbs. I'm surprised there are no cement chambers for the boxes. In years to come they will rot and cave in. That's hazardous to walk on or mow. "Potters Field." Is it possible NYC stores all the paupers who died in the winter months in a mortuary, then have a mass spring burial after the frost is out of the ground? It's common practice in northern climates.
