This striking 1949 Hungarian commemorative honors the 75th Anniversary of the Universal Postal Union (UPU), founded in 1874. Issued by Magyar Posta, the stamp features a symbolic design showing two globes linked by postal pipes, representing worldwide communication, with the classic post horn below. Printed in deep blue, it reflects the post-war era’s emphasis on global cooperation and the rebuilding of international postal networks. A desirable thematic item for UPU, postal history, and Hungary collectors alike.
