Thanks for the clarification. I stared at the photo and saw the shoes but it looked like there were yellowed bones as well. Perhaps they were sandals?
Auschwitz contains everything it did originally except the bodies. It’s also open to the public for idiots to display their idiocy. Nearby there is a lake where the bottom is permanently grey from the human ashes dumped there. There is also a field the size of two football fields that covered with ash ten feet deep. If anyone takes a smiling selfie in front of those, I would consider it bordering on evil instead of just stupid.
