In 1933 they won first place in a Mariachi contest celebrated in Guadalajara. Then again, in Mexico City, in 1934, they were awarded another first place prize. President Lázaro Cárdenas, who enjoyed the music of "Vargas", subsequently had the group hired as the official mariachi of the Mexico City Police Department and the group moved to Mexico City where they remained for 20 years. They provided music and entertainment for the capital city at its parks and gardens. Beginning in 1937, the Mariachi Vargas appeared in "Asi es mi Tierra", the first of its more than 200 motion pictures. They played in many of Pedro Infante's movies as well. In that same year they recorded their first record and signed an exclusive contract with RCA.
