If you see a painting that looks something like this at a fleamarket it might be a good idea to snap it up, someone else did and their 1,500 euros ($1,800) investment, is expected to turn into up to three million euros ($3.6 million) at an auction in France on Saturday.

The painting that they bought was a "lost" painting by Vincent Van Gogh.

Now that is the sort of return on your investment that The Green Man is aiming for. Sadly, at this stage, no Van Gogh's have come his way.
