Cadioli, B. : Mail censorship during the Italo-Ethiopian War 1935-36. In Fil-Italia #168, Spring 2016, pp72-80. This censorship began illegally as no government decree was published and the authorities criticised the use of ‘Verificato’ handstamps as they wished to keep secret their activities. Meanwhile the general public knew of, or suspected that, censorship was being carried out. The author continued his article with the censorship of military mails.
