If you're not an art connoisseur, it looks a lot like a bunch of squiggly lines on a page. But to an expert, it's a stunning find - an original Jackson Pollock, an American painter and an artist considered a master of abstract expressionism.

How this painting came to be on display and up for sale in a local Toronto gallery is the stuff of legend. You may remember the unbelievable story surrounding a woman named Teri Horton, a retired truck driver who loved to frequent thrift shops around North America. When she entered one of them in California in the 1990s, she spotted a picture lying unused in a corner, a piece of artwork that no one seemed to want.

She hated it but thought it was funny. And she was going to buy it for her depressed friend. And she brought it to the counter and the lady said it was $8 and Teri said she's willing to pay $5, she doesn't love her friend that much. They were planning on drinking some beers and throwing darts at it. But a friend of hers was dating an art teacher and he looked at it and said 'you very well may have a Jackson Pollock on your hands.'

And she came back with the statement 'Who the F is Jackson Pollock?' And it all began from there. That statement became the name of a 2006 documentary featuring her story, including her struggles to prove her five buck painting was really the masterpiece many claimed it was. It was finally authenticated and now there's no doubt about its value.The painting has since been assessed as being worth a stunning $50 million, surely the greatest flea market bargain in history.
