GREECE: Military post offices on the Salonica front. Cover fr. with 25c. french stamp, never cancelled, posted from "Vojna posta 999" with Serbian censorship "PREGLEDALA/VOJNA CENZURA (37)" with 3-line "CROIX ROUGE SERBE/BURBAU DE RESEIGNEMENTS/GENEVE, Rue Muzy 1". The Serbian military offices were not supposed to cancel French stamps. Apparently the clerks at TetP 504 were instructed that they should only cancel the stamps on registered mail. Therefore no one was authorized to cancel the stamps on unregistered mail to Switzerland. Occasionally they were never cancelled.
