Arena Naucalpan 29th Anniversary Show

The Arena Naucalpan 29th Anniversary Show was a major annual professional wrestling event produced and scripted by the Mexican professional wrestling promotion International Wrestling Revolution Group (IWRG), which took place on December 21, 2006, in Arena Naucalpan, Naucalpan, State of Mexico, Mexico. As the name implies the show celebrated the 29th Anniversary of the construction of Arena Naucalpan, IWRG's main venue in 1977. The show is IWRG's longest-running show, predating IWRG being founded in 1996 and is the fourth oldest, still held, annual show in professional wrestling.

The focal point of the show was a 12-man Ruleta de la Muerte ("Roulette of Death") tournament, consisting of two six-man matches where the loser would be forced to defend his hair or mask in the finals. In the end, Coco Verde defeated Dr. Cerebro, forcing Dr. Cerebro to have all his hair shaved off as a result of the Lucha de Apuestas, or "bet match" stipulations. The show featured three additional matches.
