Issued in 1961, this Nigerian commemorative stamp marks the nation’s admission to the Universal Postal Union (UPU), symbolizing its integration into the global postal community shortly after independence. The design features a red silhouette of an airplane flying across two stylized globes, representing international postal communication. The bold blue background enhances the contrast, while the inscription “UNIVERSAL POSTAL UNION ADMISSION 1961” emphasizes the historic milestone. This issue highlights the modernization of Nigeria’s postal services and its new role in global exchange.
