Issued by Poland in 1953, this 1.35 złoty green stamp commemorates the III Światowy Kongres Studentów (3rd World Student Congress) held in Warsaw from August 27 to September 3, 1953. The design features a torch and open book before a globe, symbolizing enlightenment, learning, and international solidarity among students. Surrounded by a laurel wreath, it reflects the post-war emphasis on peace and youth cooperation under the socialist bloc’s cultural exchanges. A classic mid-century Polish issue, it’s a fine thematic piece for collectors interested in education, youth movements, or international congresses.
