When I was back in the UK recently visiting friends and family for Christmas and New Year, I came across an original work by Banksy, the celebrated anonymous British graffiti artist, on a wall on the Portobello Road.

Today, I read a BBC News article saying that the same work of art has just been sold on eBay by the owner of the wall for £208,100!
