This Spanish definitive stamp features a formal portrait of King Juan Carlos I, who reigned from 1975 to 2014. Issued by Correos, it is part of the long-running “King Juan Carlos” definitive series printed by the Fábrica Nacional de Moneda y Timbre (F.N.M.T.). The minimalist design emphasizes the monarch’s profile, symbolizing Spain’s modern constitutional era following the Franco period. These issues appeared in numerous color and denomination variations, widely used for everyday postal purposes in the late 1970s through the 1980s.
