This interesting aerial view is of People's Park with the technical school on the left of the shot. This is now Calderdale College. Belle Vue Mansion is centre top. The growth of many trees in the park has changed the view today significantly.
The group of admirers in this photo look on at the display here. The park was one of the very many philanthropic projects by the wealthy Crossley family who were one of the largest employers in the town at their carpet factory at Dean Clough.
