Issued in 1991, this historic stamp from Croatia marks the early postal identity of the newly independent Republic of Croatia. Featuring an aircraft symbolizing airmail service (Zračna Pošta) flying over architectural elements of Zagreb, the design reflects national transition and modernization of communication. The inscription Republika Hrvatska represents one of the country’s first sovereign postal emissions following independence from Yugoslavia. Highly significant for collectors of political transition and new-nation issues, this stamp represents the birth of modern Croatian philately. A key early issue for Balkan and European postal history collections.
