There is no identification on this card but it is clearly shows a major event in Hitchin Market Place. There is a historical procession led by the Ancient Britons and Romans, the Vikings (Hitchin was part of Danelaw), and behind there is a banner referring to the ancient Manor of Hitchin. The cloths of the bystanders suggests early 20th century.

There were decorations in the market place, and a procession of float, to celebrate the Coronation of King George V in 1911.  Could this be a photograph of this event or suggest an alternative event/date?
