The Promociones Gutiérrez 1st Anniversary Show was a professional wrestling supercard event promoted by Consejo Mundial de Lucha Libre (CMLL) and Promociones Gutierrez, CMLL's local promoter in Nuevo Laredo, Tamaulipas, Mexico.

The event took place on July 12, 2010 at the Plaza de Toros Lauro Luis Longoria bullring and commemorated the 1st anniversary of Promociones Gutierrez.

The main event was a 10-man, 5-team Ruleta de la Muerte match which meant that at the end of the night one man would be unmasked.

The fifth and final team was an all-CMLL team of Averno and Último Guerrero, who as leaders of the two top rudo (bad guy) factions, Los Hijos del Averno and Los Guerreros de la Atlantida had been rivals for years.

The team was rounded out by NJPW's Jushin Thunder Liger, a light heavyweight wrestling legend who had been touring with CMLL since June.

[4] The fourth match of the show was scheduled to feature three wrestlers who had never worked for CMLL, but were not considered part of Los Invasores.

[4] The opening match featured the Mini-Estrella division as for the first time a "Mini Invaders" team was put together.

The inclusion of Mini Oriental was not a great surprise, the "normal sized" Oriental was wrestling in the main event, but the inclusion of Mini Cibernético was a surprise, especially since the "regular sized" Cibernético was one of AAA's top tecnicos (good guys).

The "Mini Invasores" would face a trio of CMLL Mini-Estrellas in Astral, Mascarita Dorada and Shockercito.

[8] Only 4 hours before the opening bell Box y Lucha Magazine reported that Dr. Wagner Jr. had been spotted in Nuevo Laredo, leading to speculations about whether he was there just to see his son or if he had actually left AAA and would appear on the show that night.

[10] The theme of "CMLL vs. the Invaders" continued in the second match as CMLL regulars Lady Apache, Lluvia and Marcela face "outsiders" Rossy Moreno and Sexy Flor, who previously worked for AAA and currently work on the independent circuit and a surprise partner that was not named before the event.

[10] The third match of the night saw the reunion of Charly Manson, Juventud Guerrera and Mr. Águila, who had worked as "the X-Team" in AAA in the early 2000s.

The former X-Team took on Rey Bucanero and Los Hijos del Averno representatives Ephesto and Mephisto.

When the referee noticed his opponent holding Ephesto's mask he mistakenly disqualified Manson, Guerrera and Mr.

Dr. Wagner Jr. came out in full wrestling gear, with the AAA Mega Championship belt strapped around his waist to the surprise of everyone in attendance.

Dr. Wagner Jr. did not make any announcements or comments during his appearance, just posing with his son and interacting with the fans before leaving the arena.

This was the match that had drawn over 80% capacity for the 12,500 seat Plaza de Toros Lauro Luis Longoria with the promise of one of the wrestlers being unmasked that night.

In the end Místico forced El Oriental to submit to his finishing move, the La Mística Fujiwara armbar combo, keeping his mask safe.

[14] After surviving the Ruleta de la Muerte match Histeria was able to put his mask on the line for a second time in the same week as he was one of 12 wrestlers scheduled to participate in the main event of Infierno en el Ring (2010), which is a cage match where the last man in the cage would be forced to unmask.
