As I was researching more and more about this Pacquebot. It so happened that I came across another Gandhi gem. This time it's Gandhi used on a cover from Mauritius.
This specific cover, MAURITIUS 1969 Gandhi Paquebot ship Pierre Lot S Africa, consists of 60c Gandhi (2), one on the front and other on the back of the cover used for airmail cover from Curepipe (JY 29) to a Pacquebot ship Pierre Lot, Cape Town, South Africa (private?) receiver, with boxed Paquebot marking.
Cover Traveled through - Land -> Air -> Land -> Sea. Very unique cover and usage.
The cover has a ton of creases and return address has been expunged. It's amazing that the cover has undergone a lot of rough weather and is still intact.
