Ever-Changing Mural

This mural is on a 3000 sq ft wall of a building in Southsea. It shows a map of the City in a stylised form which the artist first painted in 1997 but it had to be redone in 2010 after being damaged by a leaking pipe.
The artist has asked Guiness World Records to recognise his project as the world's only ever changing mural. He regularly adds to it, often with requested items by local people.
