Buy art. Can you spot a future Picasso? Buy work by young artists and hope they become famous. if that is a risk too far, try established painters and sculptors. However, be warned. You have to understand not only art but also art fashions. Not recommended, unless art really is your passion and you have lots of money! Invest in furniture or antiques. Like buying art, this is high risk and depends on changing fashions. You must know the markets well.
