Rare POSTALLY-USED Arctic Research Expedition Cover-2012-PFS Polarstern

Description

You are bidding on a unique, POSTALLY USED cover from the German oceanographic research icebreaker, PFS (Polarfahrtschiff) Polarstern, operated for the Alfred-Wegener-Institute for Polar and Ocean Research in Bremerhaven, Germany.
The ship departed Tromso, Norway on 02 August 2012 and arrived in Bremerhaven, Germany over two months later, on 07 October 2012, having spent two months in the high Arctic ocean, conducting environmental experiments and observations, including air chemistry, marine biology, physical oceanography, geological and geophysical measurements and seafloor sampling, seafloor mapping and testing of new oceanographic instrumentation.
The cover is signed by and was sent to me by the Chief Mate, and attested to on the face of the cover. The stamps were cancelled aboard the vessel by the ship's postal clerk, who is also the ship's radio operator.
The ship was later (2019-2020) the Arctic drift platform for the international multi-seasonal MOSAiC Project, spending a year frozen into the Arctic ice above 80°North Latitude
I am now 80 and such mementos are becoming a burden. I need to "downsize" before my heirs have to do it for me.
Shipping will be made in a large manila envelope with a "stiffener" inside the shipping envelope to prevent damage in transit.
Note that if you purchase more than one of my items, I will combine shipping charges.
Thanks for looking and good luck.
-------------And now, the not so "fine print"---------------------

If you can't, or do not intend to pay within 5 days, please make advance arrangements with me. All who pay on time are provided with excellent feedback at the time of payment. If you are happy with your item, I would appreciate the same.
