Lou Thesz defends the NWA World Heavyweight Title, from San Antonio TX.    Available on the Network, Vault, Hidden Gems 1951.    "Texas Rasslin: Thesz vs Gunkel, May 30, 1951"

 

So....it turns out that WWE has the wrong info for this match.  It is actually from Dallas, September 16, 1952

This is great. Thesz is such a fantastic prick in this, they somehow make the Harley Race style babyface just kills the heel champ for 90% of the match thing actually work. Amazing finish too.
