English: This unique postmark is actually a customs security seal that was placed on the shipments sent from the Soviet Union to other countries of the world. This particular shipment containing large amount of books was shipped by Mezhdunarodnaya Kniga from Moscow USSR, to People's Publishing House (PPH) in New Delhi India. This was shipped via "Odessa" is Ukraine. Although such marks were commonly used on Air Based consignments, but I believe this particular shipment was sent via sea-post. There is a date stamped on this receipt “18 September 1981”, in Russian Language (12 сен. 1981). On the top of this receipt “De Moskva PCI” is written in French. On the left side is written “Via” in English, and “Cherez (Через)” is written in Russian. In the middle “Pour” and “Poids” are written in French. On the right side “Dépêche No” is written in French and “Date” is written in English. The misprinted / torn “LC” means “Priority / Prioritaire Mail”. The “AO” means “Non Priority / Non Prioritaire Mail” and “JX” means “Journals or Magazines related mail”. This particular shipment was sent in Non Priority mail, presumably via “Port of Odessa” through Sea Post.
