But this was in 1974, and as of that moment, this photograph was the photograph that was the most widely printed, because we printed two billion copies of this photograph, and we took them hand to hand, door to door, to show people and ask them if there was smallpox in their house, because that was our surveillance system.
Pero esto era en 1974, y, desde ese momento, esta foto fue la foto que más se imprimió, porque nosotros imprimimos dos mil millones de copias de esta foto, y las llevamos de mano a mano, puerta a puerta, para mostrarla a la gente y preguntarles si tenían la viruela porque ese era nuestro sistema de vigilancia.
