Seek the Lonely Troll by Barek
Walk a little bit further down Rutledge Lane until you stop in front of an abandoned doorway.
Clue 1: Look behind the tagging
The space in which it has been put up perfectly represents the isolation the artist wants to convey through his paste up and the environment he has placed it in. Obviously over time this frequently visited doorway has received a fair amount of tagging making the Barek piece barely visible to the untrained eye.
However, this is the transient nature of street art that artists thrive on because they like that it is accessible by the public and letting the public interact with it along with letting nature taking its toll on their pieces.
