Alejandro Del Prado (Calé) was an Argentine humorist, born in Rosario. Shortly after World War II, he settled in Buenos Aires and began working in advertising. In 1947 he started a collaboration with the magazine Pobre Diablo, in which he created his series 'Buenos Aires Intimo'. This series was continued under the title 'Buenos Aires en Camiseta' in Rico Tipo from 1951. Although he was from the province of Santa Fé himself, Calé will be remembered for his clever observations of the Porteños, the inhabitants of Buenos Aires.
