FRANCE - POSTES SERBES COVER FROM CORFU 1918 (JAN) censored cover from Corfu to Switzerland bearing France 25c Sower tied by 'POSTES SERBES' single line handstamp and Cyrillic Serbian cds cancel, with Switzerland 30c Postage Due stamp tied by 'GENEVE' cds and lovely crisp boxed 'CENSURE / MILITAIRE SERBE'  and oval Serbian '309' censor cachets alongside with censor tape at left. On the back is Swiss transit mark, censor cachet and some manuscript notes in German. Small peripheral faults but an attractive and scarce cover.
