In 1900, a city photographer came to a weaving mill in Belfast, Northern Ireland, to process flax and took a high-quality photograph of 15 female workers.
Almost all the girls have their hands folded across their chest, so only more than a hundred years later people noticed that there is one extra hand in the picture and it is on the shoulder of the girl on the far right in the third row from the top.
This hand definitely does not belong to the girl who is standing behind her, as her hands are tightly folded one on top of the other.
The hand on the shoulder is quite natural. It could have belonged to the girl who was even more to the right. But there is nobody there. At the same time, it is also known that the photographer did not edit the picture in any way and did not delete the hypothetical 16th girl from it.
There are no other paranormal details in the photo. There are also no scuffs, smoke screens and so on. The picture for that time was made quite well.
The hand also does not look translucent. It looks as dense as the hands of the girls standing next to it, and you can even distinguish nails on it.
