Giant Baba defeated Jack Brisco for the NWA title on December 2, 1974 in Kagoshima, Japan. It was the first of three short reigns Baba would have with the NWA championship.
You can quickly identify that this was the title he won from Brisco (as opposed to the latter two from Harley Race) because of the way the belt looked, the true tale-tell being the white lettering on a black background above the country flags on the belt. The "Ten Pounds of Gold" book details all those small indicators that identify the version of the belt, which underwent four distinct transitions over its life from 1973-1986.
