This one is a doozy ladies and gentlemen, seemingly the perfect storm of collectable elements all crammed together into one Air Jordan. First of all, it’s an OG pair of the Air Jordan XI ‘Space Jam’, one of the most coveted colorways of all time. Second of all, Michael Jordan himself played in this pair and subsequently autographed them. And last but certainly not least, they bear the 45 on the back in place of the traditional 23, a treat that generally only pops up on pairs made for MJ himself.
