When Ric Flair made his way to the World Wrestling Federation during the summer of 1991, he brought with him the 'Big Gold Belt' that is synonymous with the National Wrestling Alliance and World Championship Wrestling.
The strap showing up on a rival promotion's TV allowed Flair - and his new employers - to point out that 'The Real World's Champion' had signed for the WWF.
A moniker claiming to be a real world champion of professional wrestling was far from hyperbole. Or, to put it in wrestling parlance: a work. Ric Flair had left his previous employers without having lost his title inside the ring. He may have also had a legal right to still be in possession of the physical belt because - as champion - the chosen wrestlers are asked to lay down a deposit as an insurance measure.
And most importantly: Flair wasn't just 'THE real world's champion'. He was the 'Last Real World Champion'.
If you're wondering why, then Tim Hornbaker's look at the career and life of The Nature Boy is the book which should lead you to that opinion.
