Scrap buyers drive through the streets of Mexico City playing a recorded call: “Se compran: colchones, tambores, refrigeradores, estufas, lavadoras, microondas o algo de fierro viejo que vendan” (We buy mattresses, drums, refrigerators, stoves, washing machines, microwaves or any old iron you want to sell).
The voice is that of María del Mar Terrón. She recorded it at the age of nine at the request of her father, Marco Antonio Terrón, who bought scrap. Sources give different years for the recording, from 2005 to about 2007. Almost all of the fierroviejeros, the scrap buyers of Mexico City, now play it.
