This Paraguayan postage stamp, denominated at 0.90 guaraníes, features a river barge laden with timber gliding along one of the nation’s great waterways. Issued under the theme “Paraguay en Marcha” (“Paraguay in Progress”), it symbolizes the country’s economic development and the vital role of river transport in linking inland regions to international trade routes along the Paraguay and Paraná Rivers. The scenic backdrop of rolling hills and calm waters reflects both natural beauty and industrious ambition, typical of mid-20th-century Paraguayan issues that highlighted modernization efforts.
