Before their burial, the deceased would be photographed in their best clothes and 'posing' (propped up) with their living relatives. In some instances, eyes were painted onto the closed eyelids of the deceased to make them appear alive. In Victorian times when photographs were rare, this might be the only photo the family had of their dearly departed.
this is a photo of 2 sisters, the one on the left has passed away. This will be the last photo & memory of their loved one. Very common in Victorian days.You can see the look of despair as the sister on the right is literally holding her beloved sister up to create a natural photo. These photographs were called "Memento Mori"
