Family Photographer Swap 2016 - ongoing

A collection of found photographs from my parent’s photo albums portraying a ritual that was always carried out in our family, where by whoever was taking a posed photograph of a group would then swap with someone else so they could be included in the shot.  It produced the uncanny result of having two almost identical photographs but with the photographer swapped in each one.
The photographs found begin in 1977, two years before I was born and run up until 2017.
