This 1939 Paraguayan official stamp was issued to commemorate the 50th anniversary of the National University (1889–1939). It features portraits of President Escobar and Doctor Zubizarreta, two important figures in Paraguayan academic and political history. Printed in red and black, the design includes a central academic emblem symbolizing knowledge. The inscription “Homenaje a la Universidad” reflects Paraguay’s tribute to higher education. A significant piece for collectors of educational and commemorative issues, as well as Latin American philately.
