Issued by Poland, this 40 groszy commemorative highlights the Międzynarodowy Kongres Studentów (International Students’ Congress), celebrating youth, scholarship, and global academic cooperation. The design features a classical student profile alongside books, a globe, and drafting instruments—strong symbols of education and international exchange. Printed in a rich sepia-brown monochrome, it carries a strong engraved, poster-style aesthetic typical of mid-century Polish issues. The bold “POCZTA POLSKA” inscription and large denomination add excellent visual balance. A desirable thematic piece for education, youth movements, and congress collectors.
