Issued by Mexico in 1970, this 40-centavos stamp highlights the nation’s agricultural productivity, particularly maize (corn), a central element of Mexican culture and economy. The modern graphic design by A. Rojas features a stylized red maize form against a geometric agricultural background, symbolizing planning and technological advancement in farming. The inscription “Qué, cómo y cuánto producimos” (“What, how, and how much we produce”) reflects Mexico’s development-oriented agricultural campaigns of the period. This issue is notable for its bold abstract style, making it attractive to collectors of agriculture, development, and Latin American thematic stamps.
