This photo of an old Trolleybus and the Black Country Living Museum seemed an appropriate upload today as it's my 40th Birthday.
From Wikipedia : "Electric trams and trolleybuses transport visitors from the entrance in a recreated factory to the village area with thirty buildings situated by the canal basin. The museum is one of only three in the UK with working trolleybuses, the others being The Trolleybus Museum at Sandtoft and the East Anglia Transport Museum near Lowestoft. Nearby Walsall retained its trolleybuses until 1970. The village is only a short walk from the main entrance, passing the Newcomen pumping engine and Fun-Fair."
