Seven-foot-one center Shaquille O'Neal was an unstoppable force on the NBA hardwood - that is, with the exception of his free-throw shooting - and wore these black Reeboks, though not likely in an actual game. Both are signed in silver Sharpie and come with an LOA from Shaq firm Mine o Mine. Besides his legendary basketball prowess, O'Neal also cultivated a career as a Billboard-charting rap star during the 1990s.
