South Africa: Aerogramme containing an enclosure

Sent from Cape Town (25 VI 1971) to Detmold, Germany, the aerogramme contained an enclosure. Boxed bilingual instructional handstamp „Contrary to Regulations“.

As an air mail letter, the item was short paid 10c, which was endorsed below the indicium. The item was returned to the sender who paid the missing 10c at the post office (red “Postage paid” handstamp).
