About one hundred years. It was my sword. I threw it into a river, I think, somewhere in the north east of France, possibly in modern day Belgium. The item currently in my possession I’ve had longest…hmm…now that is different from the item that is the oldest. My oldest possession is a chair. But the item I’ve had the longest is perhaps a photograph of me that dates from 1869, taken by one William Henry Jackson.
It exists nowhere in the world but my own hand.
