Two street artists have painted a massive 3-D public art mural of the Wall from HBO hit television series Game of Thrones. 3D Joe and Max are the creators of the hyper-realistic mural on Liverpool Street that shows climbers astride a giant wall in a frozen landscape, much like the ‘real’ 300-mile long and 700-foot-tall wall guarding the North in the series. Designed in three dimensions, the mural can be experienced from all sides. Season Four of Game of Thrones airs in the US on April 6.
