A mysterious message has appeared on the back wall of Southbank Kensington.

The Admissions Team, who are based opposite on Portobello Road, spotted the painted scrabble letters when they arrived at work on Monday morning.

It doesn¹t appear to be a Banksy, but someone has suggested it might be the work of design collaborative ³Static². Whoever is responsible probably used a ladder and managed to avoid our CCTV cameras to complete their work.

Is it urban art, graffiti, a marketing stunt, or the next clue from Lost? Tell us what you think!
