The first American Quarter Horse Association-approved show was held here on July 2-4, 1940, in conjunction with the Texas Cowboy Reunion. AQHA had just been organized and incorporated in March of the same year in Fort Worth. DEL RIO JOE, a 1936 grandson of HARMON BAKER by PETER McCUE, won the Stallions Foaled Prior to May 1, 1938 class and was named Grand Champion of the show. DEL RIO JOE was owned by Bob Denhardt and shown by Tinker Allbright. Winning the Geldings Foaled Prior to May 1, 1938 class was PUNKIN, owned by Jess Slaughter. Ramon Wood's BREEZY D was the best of the Mares Foaled Prior to May 1, 1938. JIGGS II won first in the class of Stallions and Mares Foaled On or After May 1, 1938, for his owner, George A. Clegg. Jim Minnick, first AQHA inspector, judged the show. American Quarter Horses now compete in horse shows around the world and are in demand for racing, ranch work, rodeo, recreational riding, and many other activities. AQHA is the world's largest equine breed registry, with its international headquarters in Amarillo, Texas.
