This 1971 Mexican airmail stamp honors Francisco Javier Clavijero (1731–1786), the renowned Jesuit historian whose works on indigenous cultures remain foundational to Mexican historiography. Issued by Correos de México, the design features a finely rendered portrait with soft sepia tones, typical of Mexico’s cultural commemoratives of the era. The $2 airmail denomination reflects its intended use for international correspondence. A desirable piece for collectors focusing on Latin American history, intellectual figures, or Mexican airmail issues.
