You have to look twice at these photos, before you get what’s going on
This photo, which shows a group of Irish girls was taken in Belfast in 1900. While they are sitting in front of the camera, someone else has joined them for the picture. Could not find him? Try looking at the girl who’s sitting on the far right. It seems that there’s a disembodied hand touching on her right shoulder. The picture was first published in a newspaper in Belfast as part of an article until one of the readers wrote them about the mysterious hand.
