We delved deep into our archives to find this selection of glass plate images.
But we need your help to identify the people in this nostaglic set which all have a sense of mystery to them.
The first shows a social gathering from the Hartlepool area, but where is it and which year was it take in. Who are the dancers and what was the occasion? Tell us more.
Our second glass plate goes back even further and illustrates women boiling water. Why were they doing it and where was the photograph taken.
Thirdly, we want you to help identify the May Queen and her attendants in this shot.
And lastly, where were these people off to on their bus trip. Can anyone tell us which year this is.
