From Alfred Faure in the Crozet Islands, posted from aboard the Marion Dufresne. This was sent to me by a team from Belgium's National Botanic Garden who were headed down to Crozet to carry out some research. Their cachet and signatures are on the front of the cover.
The other interesting mark on the cover is that of the team heading to Kerguelen to catalog items of historical importance: "Inventaire du patrimonie des TAAF".
An interesting side note for this cover. The Marion Dufresne ran into some rocks on its way to Crozet on 14 November 2012. Everyone was evacuated and the ship had to be temporarily repaired. It was decided that the Marion Dufresne should return to dry dock for permanent repairs so they had to end the rotation early at their first stop in Crozet.
