Boxing legend Muhammad Ali's little-known artwork fetches nearly $1 million at auction

Although Muhammad Ali has been dead for five years, he's still surprising the world. On Tuesday, 28 pieces of the legendary boxer's artwork were put up for auction — and they fetched nearly $1 million. 

Ali's art career, which comes as a surprise to many, was due in part to his old friend Rodney Hilton Brown. 

"I had taken over a failing art gallery in Soho, and I was looking for a world class famous figure that could paint some paintings that we could make limited edition prints of and sell," Brown said.
