A classic airmail issue of Paraguay, this 5 Guaraníes stamp commemorates the historic visit of United Nations Secretary-General Dag Hammarskjöld to the country. The design features the United Nations emblem in crisp white against a deep blue field, encircled by a brown airmail frame. The ribbon inscription pays tribute to Hammarskjöld’s diplomatic mission in Latin America. A desirable thematic item for collectors of UN, diplomacy, and Paraguayan postal history, often sought for its political and international-relations significance. Clean typography, bold colors, and balanced layout make this a standout mid-century Paraguayan issue.
