David,
One of the posters here awhile back showed how he had taken a photograph of a garage building to a local fast print sign shop and had them blow it up and print it to a scale size for his diorama. That got me thinking about doing the same thing with a photo of the Dunlop bridge at Le Mans, but haven't done it yet. Anyway, I thought it might be a way to get at least some urban background for either side of Hooper & Company.
