I just don't understand the idea of something like that coming out of your body and the instinct is to touch it and treat it like a specimen. The only thing I can relate it to is menstrual blood or a bowel movement or something and then just taking it into your hands. It just isn't something that would ever cross my mind to touch.
I suppose it is unnerving to me because first and foremost, I am a childfree person who would never hold a pregnancy to term, so I am not terribly familiar with what would/could/does happen with a miscarriage. It is hard for me to think of the mindset where you desperately wanted this child and ever harder for me to understand what that loss would feel like or how to cope afterwards, especially having the literal evidence right there in a case such as this where you can actually look at it.
I've always thought of miscarriages as this sad but faceless thing where maybe there is blood and discomfort but never really thought about the idea that it is possible for an actual being to be expelled from the body in a physical form. Also, just my thoughts here, it seems really disrespectful to keep it like it is a relic or to display it like this. It isn't a sideshow attraction, it was going to be OP's baby. It just seems a bit sick and twisted to me personally. This seems like a private thing that is 100% totally fine for OP to do for the grieving process if that is what OP needs to do but it seems perverse to share it with strangers like when parents show photos on facebook of naked children covered in excrement...Fine for the parents to see but way too intimate to be showing to anyone else.
I'm aware I am getting a million downvotes here but I am entitled to an opinion. I am sure it is very difficult to go through a miscarriage but showing pictures of a deceased fetus like this doesn't immediately bring me to tell OP she/he is brave and this is commendable. That doesn't mean my opinions are wrong, it just means that the situation does not move me in the same way is for others. that is all.
