I've attached a photograph that has been frustrating the family for a very long time. We're not sure what kind of date we could put to it. I think the colour of it might be a little misleading, as the photo came from my great-grandmother, who was a chain-smoker, and therefore it might look browner because of the smoke fumes.
I think maybe the only way to date it properly would be by looking at the clothes the ladies in the photo are wearing, but i have almost no knowledge of fashions through the ages.
Any help would be greatly received.
