Military post offices on the Salonica front. PS written on "22 August 1916" with Serbian censorship "(12) PREGLEDALA/VOJNA CENZURA". The PS returned to Salonique for taxed with 5l. Litho and canc. with "ΘΕΣΣΑΛΟΝΙΚΗ*5 ΣΕΠΤ. 16" and censored again with French "ARMEE DORIENT/CENSURE MILITAIRE", "OUVERT par lAUTORITE*305" and "SAISI PAR LAUTORITE MILITAIRE" to Geneve. The PS probably was held by French censor and released after 6 months for unknown reason. The linear "9 AVR. 1917" may be the date of release from French censor or may be the date of receipt in Geneva.
