Previous pinner states this is a Momento Mori of sisters held up by support stands. I do not believe this to be a post-mortem photo at all. Both sisters are looking directly at the camera. Two things to be very wary of: Claimed momento mori where the body is standing, or is looking at the camera. You can be almost 100% certain you are NOT looking at a postmortem photo. What do you think about these two children?
Civil war medical officer. Possible standing postmortem. Standing postmortems are almost unheard of with adults. This has been closely looked at by The Thanatos Archive. Conclusion? Possible standing postmortem which is pretty exciting really since they're things of legend!
Another death photo, the one in the front middle for sure, perhaps the one on the front right as well. These are actually quite common and frequently this was the only way to get your picture done unless you had money. It's called memento mori.
