Drivers heading on the various roads across the country will have noticed a number of new locations added to the signs including Middle Earth, Narnia, Gotham City and Neverland, the Sun Online reported.

Although comical, the Oxfordshire County Council has dubbed the act as ''vandalism''.

Spokesman for Martin Crabtree said: ''While on the surface amusing, it is vandalism and a potential distraction for drivers.

''We will investigate as soon as the weather improves.''

Didcot Mayor Jackie Billington said: ''Someone has obviously gone to a lot of trouble.

''You can't tell the difference, they are exactly the same font and look like any other normal street sign.

''I saw it online and thought I would go and have a look but I never made it to Middle Earth.

''I'm concerned that a tourist could be driving around for hours trying to find Gotham City.

''It is fun and quirky and gets people talking about the town again but, in all seriousness, they will have to be removed at some point and that will be an expensive job.''
