From the research station Alfred Faure on Possession Island in the Crozet Archipelago. Like the cover I received from Port-aux-Français last week, this too was carried there and back by the French research vessel Marion Dufresne during OP2 of 2019. I wouldn't be surprised if I get another one soon from Martin-de-Viviès. Perhaps a blue envelope. I still have no memory of preparing these or sending them down there.
