International Bureau of Education

The International Bureau of Education (IBE), or Bureau International d'Éducation (BIE) is an organization dedicated to that purpose. It was founded in 1925 as an independent charity. It is now part of UNESCO.

Beginning in 1930, it began a service to provide books and educational materials to prisoners of wars. Since paper and support came from the Swiss post office, the stamps are considered semiofficial. Used stamps were never cancelled. 
 * In 1940 they began using labels on the their mailings in four different colors with the inscription 'AIDE INTELLECTUEL / AUX PRISONNIERS / DE GUERRE and BUREAU / INTERNATIONAL D'ÉDUCATION. A 1942 souvenir sheet exists.
 * In 1944, the design was changed from Pestalozzi to Pére Girard.



Switzerland then granted franking power to the bureau, overprinting Swiss stamps for their use.  File:Switz B edu 15c.A.webp|1950 15c technology. File:Switz BIE engr.jpg|1960 20c Pestalozzi statue
