From the Germany Antarctic research station Neumayer III. There are a couple of hand-stamps on the back as well including one for the 38th over-wintering team of 2018. Neumayer III was officially opened twenty years ago on 20 February 2009. It is located on the Ekström Ice Shelf near an iceport known as Atka Bay. The ice port is an indentation in the ice sheet that makes it possible for ships like Polarstern to load and unload.
