This is an antique photo of two people, a man & woman, in some kind of workshop. No one wrote anything on this picture to identify the people or its age - we believe it is very early 20th century. It is mounted on a larger cardboard backing & is a little faded.
There is some sort of light above the table, but I'm not convinced that it is electric. The items on the floor near a table and a barrel look like nuts & bolts to me, but it could be anything. It has an ornate, probably tin, ceiling.
I've gone over this picture with a magnifying glass looking for anything like tools or advertising I could identify. Some of the items on the shelves have writing, but I could not read it.
I like pictures like this because of all the details in it - details no one gave a thought about. This one is full of wooden barrels, boxes, shelves with cans on them, stuff piled on the floor, and on and on. I have no idea what kind of work went on there, but it captures a fraction of a second of two people's lives. Two people who are long gone, but who look quite healthy here.
