The art story that caught our eye this week was something of a lesson in investment.

Apparently investing in property isn't the only way to see yourself right financially in years to come, as one student, who blew a considerable portion of his student loan on a painting he liked, has just proved.

Ten years roll by and the artist, known as Banksy, has become quite well known - so well known in fact that his paintings are being sold for tens of thousands of pounds.

The student, meanwhile, had the painting hung above his bed. When Sotheby's auction house on Bond Street found out Gez Smith had the painting hanging in his bedroom uninsured they sent a van to collect it immediately.

Gez made a wise - if unknowing - investment a decade ago, but will his works hold their value in time?
