Can you spot the spooky hand in this 1900s photo from a Belfast linen mill?
From the outset it looks like a normal black and white photograph - but look a little closer and all is not as it seems.
The picture from the 1900s shows 15 female workers in a linen mill in Belfast.
However, when you look closer at the picture, there appears to be a rogue hand resting on the shoulder of a girl on the right hand side.
Can you explain it?
