This is the sign seen on the end of the brick wall which was an entrance to Scatterbrook Farm. The other entrance was a gravel drive at the back of the farmhouse by the caravan with a wooden farm gate which had a long Scatterbrook Farm sign along the top.
In the series 4 episode "Choir Practice" Mr Braithwaite is driving out of the main farm entrance as John and Sue pass, so for that scene this sign was made.
The reverse has faint pencil showing what needed to be written, original nylon loops at the top.
