This is one of the 8ft fibreglass rugby balls that was built for last year's Rugby World Cup in Twickenham. There was one for each of the five home nations and they were placed in prominent parks across Richmond.
They have come back, but in different places, for this year's Six Nations tournament. The Scottish one has appeared in the corner of Ham Village Green at the junction of Ham Street and Wiggins Lane. I am not sure that it will do anything to encourage people to watch the rugby but it provides a bit of colour for the moment.
