"Flor Silvestre, the Soul of Ranchera Song". In November 1946, she was invited to perform at the inauguration of Guadalajara's Juárez movie theater. The Guadalajara newspaper El Informador described her as "Flor Silvestre, young XEW singer, who represents the feeling of our land within the ranchera song". Between 1947 and 1949, Flor Silvestre and the showman's company toured Central and South America, performing at the best nightclubs along the way. Hugo del Carril presented Flor Silvestre to audiences when the company toured Argentina. The company eventually made its way to Peru, where they performed for the Mexican Air Force, before returning to Mexico. 1950–1952: Acting debut and first records When Flor Silvestre returned to Mexico from her South American tour in 1950, her manager got her a contract to perform at Mexico City's most popular nightclub, El Patio. She later said: "Emilio Azcárraga and Gregorio Walerstein went there every day, and everyone saw me there, and they all hired me without me asking for anything, and everyone called me and called me, and that's how I started [singing] on the XEW [station]". Azcárraga, the owner of XEW, Mexico's top station, gave her her first radio program, Increíble pero cierto, which she also hosted. Walerstein, a leading film producer known as "the Tsar of Mexican films", signed her to a five-film contract. With the success of her radio program, her singing career began to ascend. Journalist Mónica Fio wrote in her column "Micrófono": Flor Silvestre made her first records in 1950 for Columbia Records' Mexican branch. She recorded at least twelve songs for the label, one on each side of six 78 rpm singles. These songs also became her first hits. "Imposible olvidarte", "Que Dios te perdone", "Pobre corazón", "Viejo nopal", "Guadalajara", and "Mi amigo el viento" were recorded with Gilberto Parra's mariachi. "Siempre el amor", "Con un polvo y otro polvo", "Adoro a mi tierra", "La presentida", "Llorar amargo", and "Oye, morena" were recorded with Rubén Fuentes' mariachi. After recording her first singles, Flor Silvestre formed a duet named Las Flores with her then-unknown sister La Prieta Linda; they recorded two songs—"Los desvelados" and "Lo traigo en la sangre" (with Rubén Fuentes' mariachi)—for Columbia. In February 1950, she was a part of the "numerous, hybrid, but useful cast" of ¡A los toros!, a revue about bullfighting staged at the Teatro Tívoli. It was written and presented by announcer Paco Malgesto,
