The crowds turned out in force when Princess Anne came to town in 1970.
Were you there and what do you remember of the day?
One picture shows the princess chatting to ladies in the crowds. Who are the women, including the lady in the wheelchair, who shared a conversation?
Union flags were waved by crowds of cheering children in another photograph. Were you one of the people standing outside the Grand Hotel on that day in May.
A third photo shows the princess sitting down to a meal inside the hotel. Were you there? And the fourth follows the princess as she pays a visit to the new shopping centre in Hartlepool.
Can you identify the people in the picture and were you one of them?
