Ghost captured in an old black and white photo

On a recently discovered photograph of the early nineteenth century, something quite unusual can be considered.

At first glance, in a picture taken in 1900, 15 women were dressed in work clothes standing near a weaving factory. But if you look closely, you can find something paranormal. Do you see a ghost among the weavers?

Here's a clue. If you carefully consider a woman in the second row from the bottom and right, you can see that on her right shoulder lies someone's hand. At the same time, all the women behind her hold their arms crossed on the chest, so the brush can not belong to any of them. Look closely:

The woman does not seem to notice (or does not pay attention) to the disembodied hand on her shoulder, and besides this, no other signs of a ghost in the photo have been found. Also, nothing indicates that the photo was edited using Photoshop. Despite the fact that a woman with a hand on her shoulder is absolutely calm, those who look at this photo are completely discouraged.
