After basketball superstar Michael Jordan sank the final free throw of Game 2 of the 1998 NBA Finals, he removed his red-and-black Air Jordan 13s in the locker room, signed each one and handed them to a ballboy.
Now, those shoes - which Jordan is said to have worn in the second half of the game - are going up for auction with Sotheby's, which expects them to fetch as much as $4 million.
