Human skin fades much after the preservation process and stretches much more than animal skin. This would mean that the manufacturer would have to be very skilled at creating an exact replica of the body and painting and retouching the skin tone. Yes, you can taxidermy a human. The ability to taxidermize a body legally and according to the following precedent is a much more complicated matter, and much of it depends on the circumstances and location.
Taxidermy is a good technique to preserve the image of the animal, but that's all: its internal parts are completely removed. And it's not that there aren't people who would like to have human remains dissected or preserved in this way. However, it is very difficult to do the right thing and all attempts in history have failed dramatically. One of the main reasons why human taxidermy is not ideal is because of the effects it would have on our skin.
When skin is preserved, human skin is known to discolor quickly. When animal skin is preserved, this is usually not a problem, since most animals have fur or feathers to cover the discoloration of the skin underneath. Human skin also becomes difficult to work with, as it becomes stiffer than animal skin. A taxidermist would have to use different tools, such as paints, to make a person with taxidermy look human.
Because the idea behind taxidermy is to make a deceased animal look realistic, this process would not be ideal. This hinders the process of human taxidermy. Although most people wouldn't want their loved ones to have a taxidermy, research is still under way if the idea of human taxidermy is possible or not. To answer your question, the short answer is that it's illegal almost everywhere you get dissected.
Ever since I've known him he has talked about wanting to be finished by a taxidermist after his death, and then putting on display in the business that started and has grown all these years - a hand-whipped ice cream shop. However, there are examples of human taxidermy; one of the most prominent stories was that of El Negro, a man from Botswana who was mounted by French taxidermists in the early 1830s. I tried to ask him last night if he knew which taxidermist he wanted to use, but his mind isn't quite there right now. If you can't determine the cause, the information you have can help your taxidermist decide if the sample can be assembled.
Hunters decorate their homes with their most impressive pieces, museums display animals, some of which are now extinct, and some collectors look for specifically old and strange-looking stuffed animals. Once you are sure that the cause of death was not illegal, take note of all the circumstances surrounding the death, and then contact your taxidermist. According to a taxidermist statement from Morbid Anatomy in Brooklyn, NY, one of them is because human skin discolors long after death and as it dries.
