During the war, mail followed complex routes, as all items were redirected to central censorship offices before being forwarded to their destination. Correspondence from Ljubljana was sent deep into Italy to centres like Bologna for examination before being returned to the postal system for final delivery. As shown on the cover below, in occupied Vojvodina, the postal service was evidently managed by the Hungarian military post at that time.
Registered cover franked with 9.00 Din, sent from Ljubljana on May 31, 1941, to Novi Sad. "Hongrie" was added in manuscript as Novi Sad was under Hungarian occupation. The letter was censored by UFFICIO CENSURA POSTA ESTERA II in Bologna (censor mark 245/II) and handled by the Hungarian military post M.KIR.POSTA 335 on June 11, 1941.
