Issued by Spain (España) in 1966, this commemorative set honors four prominent Spanish military leaders and statesmen whose service shaped Spain’s imperial and administrative history. The series features finely engraved portrait designs by Fábrica Nacional de Moneda y Timbre (FNMT), reflecting Spain’s classic mid-20th-century stamp aesthetics.
The set includes Manuel de Castro y Padilla (1.50 ptas), Antonio de Mendoza (30 cts), José A. Manso de Velasco (1 pta), and Manuel de Amat (3.50 ptas)—all key colonial or military administrators of the Spanish Empire.
Printed in rich monochrome tones with strong facial detail, these stamps are valued by collectors of Spanish history, military leadership, and portrait issues. A desirable complete set for thematic, historical, and Iberian philately collections.
