1942. THE UNIVERSAL POSTAL UNION, CONVENTIONS AND AGREEMENTS SIGNED IN BUENOS AIRES ON MAY 23, 1939. Aldu Editions. Santander, 1942. The volume is tired, and the cover, although complete, has a detached first page. This monumental work, the seed of the worldwide modernization of the postal system, includes a huge number of globally standardized forms that are still in use today.
